A comprehensive ergonomic validation of workspaces design employing digital and physical mock-ups in the case of light armored vehicle

The study aims to evaluate the compatibility of the proposed design workspace dimensions of light armored vehicle (LAV) with the targeted populations of Ethiopian army personnel using both digital and physical ergonomic evaluations. The dimensional compatibility was tested using digital mock-up interfaced with human manikin representing the anthropometries of 5th percentile female and 95th percentile male values for Ethiopian army. CATIA V5 software was utilized for developing digital human and vehicle models, while the physical mock-up was tested through minimum possible user trials (to avoid redundancy of testing) that involved 13 users sufficient to represent the target population. The intended vehicular workspaces, in terms of space adequacy, view field, reaching, and manipulative needs were found to be ideally compatible with the target users, accommodating 90% (for adjustable units) and 95% (for non-adjustable units) of them. This confirms that the proposed basic design dimensions of LAV workspaces for driver, gunner, commander, and other infantry troops are compatible with the target users in both evaluation techniques. Hence, our findings indicate that the newly proposed design dimensions can be utilized as design standards primarily for fabricating Ethiopian LAVs, as they ensure occupational compatibility for the users, which can improve crew operational performance, efficiency, and safety.

A Finite Element Analysis of a Tooth-Supported 3D-Printed Surgical Guide without Metallic Sleeves for Dental Implant Insertion

Static guided surgery for dental implant insertion is a well-documented procedure requiring the manufacturing of a custom-made surgical guide, either teeth-supported, mucosal-supported, bone-supported, or mixed (teeth-mucosal-supported), depending on the clinical situation. The guidance of the surgical drills during implant bed preparation could be undertaken using a sequence of different diameters of metal drill sleeves or, with the sleeves incorporated in the surgical guide, shank-modified drills, both clinically accepted and used with good results. Despite the great number of advantages associated with the use of guided surgery, one of the major risks is guide fracture during drilling for implant bed preparation. Therefore, the aim of the present study was to evaluate the surgical guides without metal sleeves and to simulate, with the aid of Finite Element Analysis (FEA), the use of such dentally supported guides for implant insertion. The FEA is performed in CATIA v5 software after defining the surgical guide mesh material and bone properties. A maximum stress of 6.92 MPa appeared on the guide at the special built-in window meant to allow cooling during drilling, and the maximum value of the guide displacement during drilling simulation was 0.002 mm. Taking into consideration the limits of the current research, the designed tooth-supported surgical guide can withstand the forces occurring during the surgery, even in denser bone, without the risk of fracture.

The feet of children with flat foot, normal foot and high arched foot were scanned with the Foot Secret 3D scanner in the sitting and standing positions. The scanning data were imported into CATIA v5 software for measurement, to obtain four parameters of transverse axis of medial longitudinal arch from transverse arch angle, external transverse arch angle, curvature and transverse arch cross-sectional area. There were statistically significant difference in transverse arch angle, external transverse arch angle and cross-sectional area between sitting and standing positions (p < 0.05). There were statistically significant differences in transverse arch angle, external transverse arch angle, curvature and transverse arch cross-sectional area among children with flat foot, normal foot and high arch foot (p < 0.05). The four parameters of transverse arch angle, external transverse arch angle, maximum curvature and cross-sectional area obtained by three-dimensional scanning can detect the changes of transverse axis of children's foot arch in different body positions with different foot types, which can be effectively used for the biomechanical evaluation of transverse axis of children's foot arch.

Performance analysis of meta-morphing wing

To adapt to a dynamic mission environment, morphing wings change their outer shape dramatically. As the airfoil thickness grows, the leading-edge radius advances, making the leading-edge smoother and allowing the laminar air to resist full swing separation at greater angles of attack. In this paper, the gear rod mechanism with rack and pinion is installed on the wings. In addition to the gear rod mechanism, corrugated shapes given at the trailing edge for elastic deformation. Flaps are used primarily on the leading and trailing edges of the wing to increase the lift coefficient and camber of the wing. A morphing mechanism would achieve leading and trailing edge deflection as well as airfoil thickness deflection at the same time. The morphing wing model is designed in CATIA V5 software with NACA 2415 airfoil coordinates. Designed model is analyzed in ANSYS workbench with various angles of attack such as -100, 00, 50 and 100 with velocity 50 m/s as boundary conditions. Aerodynamic efficiency CL/Cd is calculated for morphing wing and compared with convention wing. Fuel consumption is one of the performance parameters that might be developed using the morphing wing concept. This morphing wing is a brand-new mechanism concept that focuses only on the mechanism rather than the materials.

Computational study on rocket payload fairing

The payload fairing is a protective clamshell that protects the payload and the third stage during the early stages of the boost phase, when the atmosphere's aerodynamic forces may have an impact. There would be stresses, strains, aerodynamic forces, deformation, and vibrations that can be acting on the rockets as they move through space or above the earth's high-density atmosphere. As a result, it's critical to use fairing to protect the payload on board. They protect the payload from the effects of aerodynamics, deformation, and vibration. This paper presents a computational study on the rocket payload fairing using CATIA V5 software for modeling and analysis.
