Data simulation of the impact of ball strikes on the bottom of electric vehicle battery packs based on finite element analysis

As a key component, electric vehicle battery packs may suffer serious consequences from external impacts, but there is currently a lack of comprehensive data and simulation studies to evaluate the impact resistance of battery pack structures. Therefore, this article establishes a three-dimensional model of the electric vehicle battery pack through finite element analysis method, taking into account the elastic and geometric nonlinear characteristics of the material. In the ball hitting simulation, appropriate impact dynamic loads were selected to simulate the actual response and deformation of the battery pack bottom under impact, in order to ensure the accuracy and reliability of the simulation results. By analyzing the simulation results, the deformation, stress, and strain distribution at the bottom of the battery pack under ball impact were obtained, as well as the related variation patterns. It was observed that the battery pack underwent significant deformation under impact load, and stress concentration also occurred in certain areas. By analyzing the stress and strain distribution obtained, the weak areas of the battery pack can be identified, and corresponding improvement measures can be proposed to enhance its impact resistance and structural strength. These simulation results also provide reference for the optimization design of the battery pack, helping to further improve its overall working performance.

Finite element analysis of the effects of different archwire forms and power arm positions on maxillary incisors in en masse retraction using fixed lingual orthodontic appliances.

This study aimed to investigate the effects of archwire form and power arm positions on maxillary incisors during lingual en masse retraction supported by miniscrew implants, using the finite element analysis method. Sliding mechanics for lingual en masse retraction were simulated using the finite element method. Power arms were placed mesial and distal to the maxillary canine with straight and mushroom-shaped archwires. Miniscrews provided absolute anchorage for retraction force. When power arms were positioned mesial to the canine teeth, an increase in the intercanine distance was observed, while a decrease was noted when the power arms were distal to the canine tooth. Lateral incisors exhibited a greater torque loss, particularly when the power arm was mesial to the canine tooth. In the central incisors, the mushroom archwire resulted in intrusion, while the straight archwire showed an extrusion tendency. Movements in groups using the straight archwire were less controlled compared to those in groups using the mushroom archwire. The archwire form and the position of the power arm affected the torque loss and vertical position of incisors during lingual en masse retraction supported by miniscrew implants. The most controlled movement was achieved with the combination of a power arm positioned distal to the canine tooth and a mushroom archform.

Soft hand with programmable grasping mode for dexterous manipulation

Many soft hands usually preprogram desired motions using oblique actuators, which limits their motion diversity and adaptability. To achieve high compliance and adaptability, this paper proposes a novel soft hand with a hybrid actuator system that can demonstrate both pure bending and helical motions. First, the structure and actuation system of the soft hand are presented. A direct-current motor is used to rotate the actuators. A pump is used to output sufficient torque to bend the soft hand. Second, a theoretical model and Finite Element Analysis (FEA) method are used to analyze the bending performance at various pressures. Then, a control method is proposed to regulate the helical radius of the soft hand in real time by adjusting the rotation angle and pressure simultaneously. Furthermore, experimental results verify the feasibility of programmable and dexterous grasping according to the shape of objects based on the independent control of bending and helical motions.

Finite element simulation of treatment with locking plate for distal fibula fractures.

An improved Finite Element Model(FEM) is applied to compare the biomechanical stability of plates with three different options in the treatment of distal fibula fractures in this study. The Computed Tomography(CT) scan of the knee to ankle segment of a volunteer was performed. A 3D fibula FEM was reconstructed based on the CT data. Three different loads (uni-pedal standing, torsion, and twisting) were applied, the same as in the experiments in the literature. The stresses and strains of the three options were compared under the same loads, using a 4-hole locking plate (Option A), a 5-hole locking plate (Option B), and a 6-hole locking plate (Option C) in a standard plate for lateral internal fixation. The simulation results show that all three options showed a stress masking effect. Option C had the best overall biomechanical performance and could effectively distribute the transferred weight. This is because option C has greater torsional stiffness and better biomechanical stability than options A and B, and therefore, option C is the recommended internal fixation method for distal fibula fractures. The Finite Element Analysis(FEA) method developed in this work applies to the stress analysis of fracture treatment options in other body parts.

Synthesis and Characterization of Metal Complexes [M(L)(Im)]NO3, In Vitro DNA/BSA Binding Behavior and Cytotoxicity on HepG2 Cancer Cells

AbstractA new ligand (HL) was prepared from heterocyclic 8‐Hydroxy‐2‐quinolinecarboxaldehyde and 2‐Aminobenzophenone in one pot synthesis. The metal complexes of the types [Zn(L)(Im)]NO3 (1), [Cu(L)(Im)]NO3 (2) and [Co(L)(Im)]NO3 (3) were prepared by adopting HL and Imidazole under refluxing conditions. The HL and complexes 1–3, were characterized by CHN elemental analysis and spectroscopic methods 1H NMR, 13C NMR, FT‐IR, ToF Mass. The spectroscopic studies suggest square pyramidal geometry in all complexes. The interaction of ligand and complexes with DNA and BSA was conducted by UV‐vis absorption and fluorescence spectroscopy. The Kb value of 2.17×104 M−1 for complex 2 is the highest depicting its greater binding propensity with DNA. Similarly, in BSA binding studies, complex 2 shows greater binding potential in the hydrophobic core probably near the Trp 212 in the subdomain IIA. Furthermore, the complex 2 shows excellent cytotoxicity on HepG2 cancer cells with IC50=74.05±0.69 μM. In the cell cycle analysis of HepG2 cells, it has been observed that complex 2 arrests the cell proliferation in the G1/S phase. Annexin V‐based flow cytometry analysis further indicated 6‐fold apoptotic cell death by complex 2 in the experiment along with non‐specific necrosis cell death.

The noteworthy tensile plasticity and strength of CoFeSiB metallic glass fiber reinforced epoxy composites

AbstractMetallic glass fibers have high strength, poor plasticity and low Young's modulus. In this study, it was used as a reinforcement to prepare metallic glass fiber reinforced epoxy composites with different fiber volume contents (20%, 30%, 40%, and 50%). The effect of fiber volume contents on the tensile properties of the metallic glass fiber reinforced epoxy composites was studied by experiment and the finite element analysis method. The experiment and simulation results are in good agreement. The tensile strength and plasticity of the metallic glass fiber reinforced epoxy composites increase with the increase of fiber volume contents. When the fiber volume content is 40% or 50%, a sharply necking feature appeared on the fibers and exhibited improved plasticity, due to the formation of interacting and arresting events of shear bands occurring at the interface between the metallic glass fibers and the epoxy. In addition, the strain hardening due to plastic deformation of the metallic glass fibers further enhanced the tensile strength of the metallic glass fiber reinforced epoxy composites. This is a first step toward toughening the inherently brittle metallic glass fibers under tensile conditions.Highlights A novel CoFeSiB metallic glass fiber reinforced epoxy resin composite The increase of fiber volume fraction improves the tensile strength and plasticity of fiber reinforced composites. The strain hardening due to plastic deformation of the metallic glass fibers further enhanced the tensile strength of the metallic glass fiber reinforced epoxy composites.

The Inclusion and Initial Damage Inspection of Intelligent Cementitious Materials Containing Graphene Using Electrical Resistivity Tomography (ERT)

This paper examines the theoretical foundations of electrical resistivity tomography (ERT) technology, followed by the finite element analysis method, for the positive problem and the linear back-projection (LBP) procedure for the inverse problem. The conductivity distribution image of the modeled concrete is then reconstructed, which includes one circular aggregate and the surrounding mortar. It is discovered that the conductivity obtained can be used to find the inclusive aggregate, mortar, and interfacial transition zone (ITZ). Natural aggregate and mortar have conductivities of 0.046 ms/cm and 0.115 ms/cm, respectively. Additionally, the conductivity of the ITZ, which is always regarded as the initial damage, is about 0.081 ms/cm. ERT is a cost-effective and readily available technique for determining the initial distribution of the aggregate and related ITZ. Therefore, ERT is a promising tool for determining inclusions and initial damage in concrete.

Synthesis of bilaterally thiadiazole substituted vic-dioxime ligands and investigation of their polymeric metal complexes

In this study, three novels substituted 1,3,4-thiadiazole-derived vic-dioxime ligands and their corresponding polymeric transition metal (Co2+and Ni2+) complexes were synthesized and their structural characterizations were performed. For this purpose, 4,4′-bis(chloroacetyldiphenyl) ether (OKS1) was obtained from the reaction of diphenyl ether with chloroacetyl chloride at a 1:2 molar ratio with the help of the Friedel-Crafts reaction. Our first starting oxime compound “2,2′-(oxybis(4,1-phenylene))bis(N‑hydroxy-2-oxoacetimidoyl) chloride (OKS2)” was obtained from the reaction of OKS1 with butyl nitrite at a 1:2 molar ratio under the catalysis of HCl gas. Then, our final starting vic-dioxime compound “2,2′-(oxybis(4,1-phenylene))bis(N‑hydroxy-2-(hydroxyimino) acetimidoyl) chloride (OKS3)” was obtained from the reaction of OKS2 with hydroxylamine hydrochloride in ethanol media at 40 °C. Then, our three original target vic-dioxime compounds (OKL1-OKL3) were synthesized from the reaction of substituted 2-amino-1,3,4-thiadiazole compounds with OKS3. Structural characterizations of all synthesized organic compounds were made using elemental analysis, FTIR, 1H and 13C NMR and mass spectroscopy methods. Target complexes were obtained from the reaction of all ligands with MCl2.nH2O (M: Co2+and Ni2+) salts, and their structures were elucidated using FTIR, magnetic susceptibility, thermogravimetric analysis, elemental analysis, and ICP-OES spectroscopy methods.

A Finite Element Analysis Study of Influence of Femoral Stem Material in Stress Shielding in a Model of Uncemented Total Hip Arthroplasty: Ti-6Al-4V versus Carbon Fibre-Reinforced PEEK Composite

Total hip arthroplasty is one of the most common and successful orthopaedic operations. Occasionally, periprosthetic osteolysis associated with stress shielding occurs, resulting in a reduction of bone density where the femur is not properly loaded and the formation of denser bone where stresses are confined. To enhance proximal load transfer and reduce stress shielding, approaches, including decreasing the stiffness of femoral stems, such as carbon fibre-reinforced polymer composites (CFRPCs), have been explored through novel modular prostheses. The purpose of the present study was to analyse, by the finite element analysis (FEA) method, the effect that the variation of material for the distal part of the femoral stem has on stress transmission between a modulable prosthesis and the adjacent bone. Methods: Through three-dimensional modelling and the use of commercially available FEA software Ansys R2023, the mechanical behaviour of the distal part of the femoral stem made of CFRPC or Ti-6Al-4V was obtained. A load was applied to the head of the femoral stem that simulates a complete walking cycle. Results: The results showed that the use of a material with mechanical characteristics close to the bone, like CFRPC, allowed for optimisation of the transmitted loads, promoting a better distribution of stress from the proximal to the distal part of the femur. This observation was also found in some clinical studies in literature, which reported not only an improved load transfer with the use of CFRPC but also a higher cell attachment than Ti-6Al-4V. Conclusions: The use of a material that has mechanical properties that are close to bone promotes load transfer from the proximal to the distal area. In particular, the use of CFRPC allows the material to be designed based on the patient’s actual bone characteristics. This provides a customised design with a lower risk of prosthesis loss due to stress shielding.

Innovative design addressing complex airway stenosis: Multidimensional performance assessment of a novel Y-shaped airway stent

“Y-shaped” airway stents have been widely used in the treatment of airway diseases, especially airway stenosis, due to their excellent flexibility. However, the current research on the flexibility of “Y-shaped” airway stents is still blank, limiting the possibility of improving the performance of stents in complex clinical disease. This study aimed to establish multi-dimensional evaluation of the flexibility of a novel segmented “Y-shaped” airway stent and two kinds of conventional stents. We evaluated the flexibility of the segmented stent, wholly knitted stent, and silicone stent by in vitro mechanical testing and finite element analysis methods. That is, the bending force and spring-back force of three kinds of stent were measured in left–right, anterior-posterior and longitudinal directions. The torque of the stents in torsion-recovery test of branches of stent was also executed. Finite element analysis was performed to evaluate the change of diameter. According to the detection, the bending force and spring-back force of the branch of the segmented stent during left–right and anterior-posterior compression, and the torque during torsion and recovery were lower than those of the other two stents. In finite element analysis, the diameter change of the segmented stent was minimal among the three stents. The flexibility of the segmented “Y-shaped” airway stent was better than that of the conventional “Y-shaped” airway stents, indicating that it has better adaptability and resistance to compression when implanted in the body.

Study on seismic performance of SRC frame-bent structures in CAP1400 nuclear power plants

With the conventional island turbine plant project of a CAP1400 nuclear power plant (NPP) as the research background, this paper proposed to apply steel reinforced concrete (SRC) frame-bent structure system to the main building of the NPP. Substructures comprising three frames and two spans from the prototype structure were identified for testing, and a test model was constructed at a scale ratio of 1/7 to test the dynamic and pseudo-dynamic characteristics of the substructures. On the basis of the test results, the structure was further verified using the finite element analysis method. The results showed that the first three modes of substructure were respectively lateral translation with torsion, longitudinal translation with torsion and torsion; The ratio between the third-order and first-order mode cycles was 0.72, indicating that the torsional stiffness of the structure was relatively small and the torsional effect was obvious. When the maximum acceleration peak was 2200 gal, the maximum inter-story drift ratio of the model structure reached 1/31. Ultimately, when the structure was finally destroyed, the concrete at the bottom of each SRC column was crushed and peeled off.

Development and Performance Analysis of Commercial Vehicle Axle Shaft

Axle shafts, which are an important part of the vehicle's powertrain system, transfer the torque to the wheels and enable the vehicle to move. In this respect, the design of the axle shaft to be used in a new vehicle is of great importance for vehicle manufacturers. When a cylindrical shaft is torsionally loaded, the shear stress is highest at the surface of component and zero at the center. Therefore, these axle shafts are exposed to an induction hardening process that enables only this superficial case to have its properties changed, remaining the core zone with its material original characteristics. Current study presents the results of a project aimed at developing and evaluating the fatigue life of axle shaft that belongs to a commercial vehicle. Developments were made on the existing axle and the results were examined using experimental tests and finite element analysis method. In line with the improvements made, the developed axle shaft has 331.7% more fatigue life than the existing axle, while the cost is 24% lower. According to these results, more attention must be paid to material selection, induction hardening process, stress concentration and surface condition of axle shaft in the design. This study involves many disciplines such as design, manufacturing, analysis, testing, etc. It is very important to ensure communication between all these disciplines in the production of the product. The output obtained from one discipline becomes the input of another discipline. In the cumulative sum of all these inputs, the optimum level of parts is obtained. For this reason, this study, which processes all these disciplines together, is very valuable.

In this study; a new heterometallic compound defined by the open formula [Cd(H2O)2Ni(CN)4]4[Cd(H2O)4Ni(CN)4]5 was synthesized in crystal form. Consisting of components such as water molecules, [Ni(CN)4]2− anions, and cadmium transition metal atoms, this new crystal structure has no analogues which might have been previously obtained, even with other transition metal atoms. It is a new compound and a unique example of a crystal. The structural properties of this heterometallic compound have been characterized by single crystal X-ray diffraction spectroscopy (SC-XRD), FT-IR spectroscopy, thermal analysis and elemental analysis methods. According to the data obtained from the SC-XRD technique, this heterometallic compound has a monoclinic crystal system and a C2/c space group. The asymmetric unit of this compound consists of five Cd(II) ions, five Ni(II) ions, eighteen cyanide ligands, and fourteen coordinated water ligand molecules. In addition, theoretical calculations have been made with the Gaussian 03 program in order to obtain more information about this heterometallic Hofmann-type-like compound. The chemical properties of this new compound have been calculated using its HOMO and LUMO values and the natural bond orbital (NBO) analyses. In addition, Hirshfeld surface analysis of the asymmetric unit of this compound has been performed with the CrystalExplorer program. As a result of the Hirshfeld surface analysis, extensive information has been obtained about the weak intramolecular and intermolecular forces that form this new crystalline compound.

Synthesis, Characterization and Application of New Polymers Imprinted with Zinc (II) Ions

In this work, molecularly imprinted polymers with zinc imprints and their comparison polymers without imprints were synthesized. A comparative characterization of the physical parameters of the synthesized zinc-imprinted (ZnIP) and non-imprinted (NIP) polymers was carried out using the methods of elemental analysis, conductometry, scanning electron microscopy, and IR-Fourier spectroscopy. The ability of the resulting polymers to molecularly recognize zinc was evaluated. Based on experimental data on static adsorption, the adsorption capacity of ZnIP and NIP was determined using an atomic emission spectrometer. It was found that ZnIP is characterized by better physical parameters and a higher ability for molecular recognition of zinc compared to NIP. ZnIP with zinc imprints were found to have better sorption capacity for zinc than their reference polymers. The sorption of zinc by molecular imprinted ZnIP is mainly due to the complex formation and pores of the initial carbon product. The synthesized ZnIP have increased porosity. The presence of pores with a diameter <50 nm in ZnIP is associated with voids formed after acid hydrolysis, which is clearly visible in images recorded by scanning electron microscopy. Thus, the possibility of using ZnIP as a selective sorbent has been established.

Research on 3D printed titanium alloy scaffold structure induced osteogenesis: Mechanics and in vitro testing

Several methods exist for repairing mandibular segmental bone defects, typically employing the implant method to accomplish the repair. Following a comparative analysis, the Ti6Al4V structural scaffold implant was chosen for bone defect repair. Triply periodic minimal surface (TPMS) is characterized by a high surface area to volume ratio, an average curvature of zero, and other notable advantages, providing a new line of thinking for bone tissue scaffolds. In this work, the in vitro osteogenesis of a cell unit measuring 4 mm was investigated. First, the finite element analysis (FEA) method and the mechanical experiment method were employed to screen the elasticity modulus of the cancellous bone of the mandible. Subsequently, the selective laser melting (SLM) technique was adopted to prepare three different structures precisely - Gyroid, octahedron, and cube - each with wall thicknesses of 0.3 mm, 0.4 mm, and 0.5 mm. In the in vitro osteogenic experiments, it was observed through confocal laser scanning microscopy (CLSM) that each scaffold displayed favorable cell spreading at 1 day and 3 days. Moreover, osteoblast cell adhesion and proliferation assays revealed improved cell adhesion and proliferation with prolonged co-cultivation time, signifying the excellent biocompatibility of the structural titanium alloy scaffolds. Furthermore, findings from cell differentiation and bioactivity assays indicated that the Gyroid structure exhibited superior osteogenesis compared to the cube and octahedron structures. However, no statistically significant difference was noted between varying wall thicknesses within the same structure.

Fiber bundle deposition model and variable speed printing strategy for in-situ impregnation 3D printing of continuous fiber reinforced thermoplastic composites

In the in-situ impregnation 3D printing of continuous fiber reinforced thermoplastic composites (CFRTPCs) at constant printing speed, in order to pursue higher printing efficiency, a higher speed for printing is adopted generally, which has no effect on the printing of the straight section, but at the same speed of printing at the corner, the printing speed will cause the fiber bundle to deviate from the printing path at the corner, which affects the accurate laying of fiber bundle along the printing path. Obviously, reducing the printing speed is an effective method to improve the print quality at the turn, but printing the entire part at the reduced speed will greatly limit the overall printing speed. However, the problem of different corner angles and shifting points from the straight section of high-speed printing to the corner section of low-speed printing has been puzzling researchers. In this paper, a fiber bundle deposition model has been proposed to reveal the deposition of fiber bundles, and the maximum offsets of fiber bundles were predicted under different turning angles. Compared with the measured results, the prediction error at different turning angles ranged from −1.07 % to 10.30 %. Then, combining with the finite element analysis method, the fiber bundle deposition model was adopted to study the effects of printing speeds, and the maximum printing speeds for different printing angles and the variable printing speed strategy have been put forward. The results have revealed that, by using the optimized variable printing speed strategy, the surface quality of the fabricated parts and the deposition of the fiber bundles along the designed printing path were significantly improved. The fiber bundle deposition model and the variable speed printing strategy could be helpful for the high-precision 3D printing of CFRTPCs.

Finite element analysis with deformed shape constraints generated by laser‐scanned point clouds

AbstractThis article proposes a computational method for finite element analysis with deformed shape constraints for analyzing constructed structures to account for deformations that occur before shape measurement by a terrestrial laser scanner (TLS). In this method, point clouds obtained by a TLS are considered as a partial surface of the deformed structure. An analysis model is assumed to be created from CAD data or drawings. The analysis is performed under deformed shape constraints, namely, the deformed surface constraints or the normal vector constraints, which are generated by the point clouds. These constraints are introduced to reproduce the current displacements and stresses for the structure through the analysis. This method was applied to analyses of a plate and a desk using point clouds, which were created virtually on a computer or obtained by a TLS in the numerical examples. The results showed that this method can consider unexpected deformations that occur before laser scanning. Although the computed stresses oscillated when the scanned point cloud was used due to measurement errors and conventional point cloud processing methods, the stress values were responsive enough to indicate unnatural shapes of the deformed structure. Moreover, the oscillation was observed only in areas with constraints, whereas it was not seen in areas without constraints.

Structural Analysis of AlAinSat-1 CubeSat

This paper presents the process of conducting the structural analysis of AlAinSat-1 CubeSat through a numerical solution using Siemens NX. AlAinSat-1 is a 3U remote-sensing CubeSat carrying two earth observation payloads. The CubeSat is scheduled for launch on SpaceX Falcon 9 rocket. To ensure the success of the mission and its ability to withstand the launch environment, several scenarios should be analyzed. For AlAinSat-1 model the finite element analysis (FEA) method is used, and four types of structural analyses are considered: modal, quasi-static, buckling, and random vibration analyses. The workflow cycle includes idealizing, meshing, assembling, applying connections and boundary conditions, and eventually running the simulation utilizing the Siemens Nastran solver. The simulation results of all analysis types indicate that the model can safely withstand the loads exerted during launch. Also, the numerical results of the Command and Data Handling Subsystem (CDHS) module of AlAinSat-1 are experimentally validated through a vibration test conducted using an LV8 shaker system. The module successfully passed the test based on the test success criteria provided by the launcher.
