Field measurements of wind load effects in a photovoltaic single-axis tracker mounting rail

The demand for solar photovoltaic power installations has resulted in a highly competitive industry. Equipment suppliers are under pressure to reduce design margins for projects to be feasible. Single-axis trackers are widely used to increase yield and reduce the levelised cost of energy compared to fixed-tilt installations. Load coefficients on tracker arrays are usually quantified using model-scale studies conducted in atmospheric boundary layer wind tunnels. These dynamically sensitive structures have been known to suffer wind damage despite the use of modern design methods. Ongoing research into the support structure design is deemed important to ensure long-term reliability. The current study presents full-scale field data acquired over 109 days on an experimental one-in-portrait single-axis tracker facility located in the Western Cape, South Africa. The purpose of these measurements was to quantify wind load effects in two instrumented PV module mounting rails. Frequency domain data showed modal participation of both the torsional and bending modes of the torque tube. The effect of the bending mode was more pronounced for the rail furthest from a pile. Load coefficients calculated using experimental data were generally lower than those presented in ASCE 7-22. Fluctuating stresses at critical locations led to negligible fatigue damage.

Emotional design of traditional Chinese cultural creative products based on user demand

Mortice-tenons are the main structural forms of ancient buildings, furniture, and woodwork in China. They are the inheritance of China's craft and cultural spirit, follow the principles of mechanics and have strong practicability. How-ever, mortice-tenons have gradually disappeared from modern life, mainly be-cause they cannot meet the specific needs of users. The purpose of this study is to establish a set of mortice-tenons structure innovation and product design for modern people. By analyzing the types and structural characteristics of mortice-tenon structure, based on the user's needs, using modern creative design methods, and combining with practice, we can verify how to further improve the market acceptance of mortice-tenon structure innovation prod-ucts, constantly explore the combination of modern technology and material experiments, and explore the emotional design of China traditional cultural creative products. Finally, it is proposed that further research is needed in this field to fully understand the user's behavior of using mortice-tenon structure innovation products, and at the same time, mortice-tenon structure innova-tion is applied to daily necessities and furniture products to meet the needs of a wider range of user scenarios.

Full Modification Control over Retrosynthetic Routes for Guided Optimization of Lead Structures.

Synthesizability is essential for compounds designed in silico. Regardless, synthetic accessibility is often considered only as an afterthought in the design and optimization process. In addition, the trend with modern computer-aided drug design methods is going toward full automation and away from the possibility of incorporating user knowledge. With this work, we present the second major release of our software tool, Synthesia, for synthesis-aware lead structure modification, where the user's expertise is now fully utilized. A provided retrosynthetic route is used as a pathway to guide structural modifications that introduce desired structural changes in the target compound. Moreover, the approach allows the user to define the exact position or component in the retrosynthetic route, which should be modified, further integrating the user's expert knowledge. This paper describes the functionality of Synthesia, its basic concepts, and several application scenarios ranging from simple examples to a comparison of the effects of the different exchange functions to an analysis of a set of bioisosteric linker structures, highlighting potential synthetically feasible replacements.

Bolt-connected prefabricated cross-shaped I-steel tower crane foundation.

Traditional tower cranes cannot meet the sustainable development goals as they use the cast-in-place concrete foundation, with large size, long construction period, and demolition after construction, resulting in waste of resources and high costs. This paper proposes a bolt-connected prefabricated cross-shaped I-steel tower crane foundation. It offers significant advantages in terms of convenient connection, low amortization cost and recyclability. The split connection point of the foundation is determined through the force analysis of the I-steel. With the ratio of the fixed cross-sectional area to the web height-to-thickness ratio (i.e. total cost) being constant, the inertia moment and bending stiffness of the I-steel are optimized using modern optimization design methods with the ratio of the web plate area to the total section area of the I-steel as the design variable, yielding the ideal strength and stiffness of the I-steel section.

Structuralism perspective to interpret the patterns and meanings found in vernacular architecture

Patterns and meanings are one of the formal architectural objects commonly studied by academics and practitioners. However, the philosophy, theory, and concept of structuralism underlying architectural patterns and meanings as a complex and diverse issue have not been conducted. Therefore, it is important to carry out in-depth studies in the context of structuralism on these objects. This theoretical study reveals the relationship between vernacular architectural patterns and the influencing philosophical, theoretical, and paradigm factors using the literature review method. Based on the notion of structural thought elaborated with architectural theory in the context of form, function, and meaning, three approaches were formulated, namely formalist, genetic, and dynamic structural approaches to reading architectural patterns and traditional meaning forms. The results showed that this study has succeeded in presenting a new reading tool to parse the patterns and meanings of a relatively complete vernacular architecture starting from the philosophical, theoretical context to the underlying paradigm. These results are expected to be useful as a new reading tool for vernacular architectural patterns. Similarly, the expected implication is as a modern architectural design method.

Historical structure design method through data analysis and soft programming

The present study is focused on the method of designing historical structures through data analysis and soft programming. The current research aimed to find the design method of the old columns of the structure and compare it with modern design methods. The case study was Goharshad Mosque (1400 AC) located in Iran, Mashhad. A correlation matrix was created to find the relationship between structure parameters by data mining in Python. The results indicate that the modern design method was more reliable than the old method due to the safety factor, but some parameters such as loading calculation in the historical method and the modern method were the same with more than 70% similarity. But the results of the coefficient of determination show that the loading of the R2 results was more than 0.44 and the area of the columns was more than −0.5. The modern and old design has a big engineering gap. Finally, the current study shows the old structure design method and compares it with the new design method.

Application of Topological Methods in the Development of Vehicle Components

Many areas of the industry are characterized by continuous changes, which define new directions of development in product design. The development of computers and software, the spread of modern production tools and the development of material technology make it possible to expand traditional production technologies with modern processes. Integrated CAD systems have occupied their place in the product design and development process for decades, reforming classical design methods. Popular optimization procedures in integrated CAD systems, such as shape optimization, topological optimization and the new generative design process, provide effective solutions for design engineers in more and more industrial application areas. Experience shows that modern design methods can be used in many areas of industry. The appearance of metal powder printing and additive technology make it possible to test the designed prototypes or even to produce the final products. The following article aims to support the above with the help of a case study.

Elastic metasurface for flexural wave refraction based on acoustic black hole

This letter presents a thin plate structure with an acoustic black hole (ABH) sub-unit to reorient the flexural wave. Different from the previously reported flexural wave metasurface, ABH sub-units are introduced into thin plates in this work, which can control the group velocity of flexural waves and realize their efficient transmission. According to generalized Snell's law, the mechanism of phase shift of transmitted waves across subwavelength sub-units is theoretically revealed. An analysis of the ABH sub-units is established by the finite element method. The deflection and focusing effect of flexural waves are demonstrated. Furthermore, adjusting the black hole section can quickly obtain the transmission phase response in the range of 2π, and it can accurately predict the phase shift and amplitude of the transmitted wave. The results show that the ABH beam-plate structure can effectively control the propagation direction of flexural waves, which provides a modern design idea and method for the manipulation and energy harvesting of the flexural wave.

Purpose. Improve the design and pressure characteristics of the centrifugal radial fan (CRF), reduce costs and design time by using modern design methods. Methods. Analytical study of the energy characteristics of the CRF using CFD software packages. Three-dimensional modeling of the flow of air in the flow part of the fan. Results. The paper describes the peculiarities of construction of the pressure characteristic of a centrifugal radial fan using the ANSYS CFX program. Numerical simulation of the flow was carried out to improve the initial indicators at the preliminary stage of the design of the CRF. This approach allows reducing costs and design time compared to the experimental approach and provides an opportunity to improve and analyze the performance of the fan and its design without manufacturing it. The use of a calculation complex of programs for the justification and analysis of the design results provides an opportunity to see the picture of the pressure distribution along the flow part, the field of velocity vectors and the movement of the air flow. By means of numerical modeling of the spatial air flow in the flow part of the fan, choosing the SST-turbulence model, the regularity of the change in the pressure characteristic of the fan was the distribution of velocities and pressures in different elements of the air conditioning system, at different values of the mass flow of air, was determined. An analysis of the change in total and static pressure in the flow part of the CRF was performed: in the stator – an inlet nozzle, in the rotor – a closed type impeller, and in the stator – made in the form of a snail. The question of the dependence of the total and static efficiency on the mass flow rate of the fan is also considered. Conclutions 1. Studies of the process of construction of the pressure characteristic of the CRF showed that the proposed approach allows you to reliably estimate the parameters of the fan’s operating modes, determine the main features of the change in determined. As a result of the calculation, efficiency and the distribution of full and static pressure in the elements of the flow part for its further improvement. 2. A distinctive feature of the proposed method of constructing the pressure characteristic is that in the early stages it is possible to predict the hydrodynamic parameters of the flow part of the designed fan without creating its solid-state model. And based on the results of a numerical study of the spatial air flow, it is possible to quantitatively and qualitatively analyze the elements of the flow part of the fan and specify their geometric dimensions for further calculation based on average parameters. 3. The ANSYS 19.0 CFX software complex allows you to immediately display changes in the design of fan assemblies and obtain the results of a numerical study of the spatial air flow in the flow part of the fan. Using the proposed graphic materials, it is possible to visually observe the processes taking place in the flow part of the CRF. The possibility of numerical calculation of the parameters of interest is also shown. 4. The creation of a real CRF to evaluate its performance requires significant funding and is time- consuming, while the use of CFD is fast and cost- effective. The ANSYS 19.0 CFX software package makes it possible to visually present a picture of the behavior of a wide range of process parameters that occur in the flow part of the fan and to show their relationship with the features of the geometry and dimensions of the fan. Keywords: total pressure, static pressure, nozzle, impeller, volute, CFD, mass flow, total efficiency, static efficiency.

Modern Design Methods on Optimised Novel Aluminium Profiles

Within the framework of optimisation of structural elements, in the last years, significant activity has been demonstrated towards developing new sectional designs beyond standardised forms aiming to combine aesthetic innovation, material efficiency, and weight over stiffness, together with structural reliability and manufacture cost savings. Moreover, in terms of sustainability performance, as material-weight reduction leads to less carbon emissions from production to installation processes, the pursuit of suitable materials that can correspond to this challenge becomes imperative. In this context, aluminium is lightweight and corrosion resistant, but due to its low elastic modulus, an increased cross-sectional stiffness is required. In this paper, 16 previously optimised aluminium cross-section profiles are presented and analysed using the finite element analysis software ABAQUS. The obtained ultimate compression resistances were compared with the predictions made in accordance with Eurocode 9, the direct strength method (DSM), and the continuous strength method (CSM). The percentage of difference of these design methods with respect to FE results is depicted. The outcomes point out the vagueness in accuracy of the prediction methods, particularly in reference to stocky or slender cross-sections.

Product Shape Design Scheme Evaluation Method Based on Spatial Data Mining

The stage of product modeling design implies a lot of complex tacit knowledge, which is the embodiment of the design concept centered on product modeling design and is also the hot spot and difficulty of modern design theory and method research. Aiming at the evaluation and decision of product modeling design scheme, a decision-making method of approaching ideal solution ranking based on grey relational analysis was proposed, which realized the convergence of tacit knowledge. The empty association rule is an important knowledge content of spatial data mining. A fuzzy genetic algorithm can solve the characteristics of random and nonlinear problems and solve the data mining problems of spatial association rules. The fuzzy genetic algorithm of discrete crossover probability and mutation probability is applied to data mining of spatial association rules in a spatial database, the coding method of the fuzzy genetic algorithm and the construction of fitness function are discussed, and the process of mining spatial association rules is given. The results show that the method of mining s association rules with the fuzzy genetic algorithm is feasible and has higher mining efficiency. This paper discusses the construction method of designing a decision support database based on linear regression and neural network and then proposes a decision method combining TOPSIS and grey relational analysis, which comprehensively considers the position and shape of the scheme data curve.

Analogous Mode Implementation of State Space Based Control of Buck Converter

Abstract The new requirements for point-of-load converters include the dynamic behavior, leading to the need for improvements in the control system for the conventional buck converter. Usually, the regulator design, in order to secure stability at parameter or mode variation, aims a zero steady-state error and a phase margin over 60 degrees. The design based on Venable’s K-factor method (Venable, 1983) helps achieve this topic. A more modern control design method based on State Space is used progressively on digital platforms. This paper extends the merits of the State Space based design procedure with an analogous mode implementation.
