Mechanics of Advanced Materials and Structures, Journal Year: 2024, Volume and Issue: unknown, P. 1 - 27

Published: March 24, 2024

In this article, seven recently developed metaheuristic algorithms are utilized for optimal design of dome-shaped trusses with natural frequency constraints. These social network search, jellyfish search optimizer, equilibrium teaching-learning-based optimization, grey wolf colliding bodies and the improved optimizer. This study focuses on assessment tuning these to enhance both computational efficiency solution quality. particular, we introduce a hyperparameter procedure that significantly improves performance make them more suitable structural optimization problems. The selected is studied through five benchmark examples dome structures, from small-scale large-scale cases, Many combination scenarios in each example order provide comprehensive statistical results determining sufficient number analyses as well particles find an efficient condition algorithm. Indeed, also presents insight into setting hyperparameters algorithm, leading better lower cost. Furthermore, comparison solutions obtained current previous studies demonstrate suitability algorithms.

<div class="section abstract"><div class="htmlview paragraph">Using SolidWorks software's precision capabilities, an initial 3D digital model of the tire changer was constructed and then imported into Ansys for static structural analysis. By applying different meshing forms to bow-shaped component executing exhaustive array load simulation solutions, total deformation distribution maximum principal stress were obtained, enabling assessment its response under operating conditions. According results solution calculations, obtained from hexahedral-dominated method nearly identical those surface method. Based on finite element analysis results, optimization design carried out changer, mainly through reinforcement local hollow achieve increase strength weight reduction. This approach effectively tackled issue easy bending breaking bow arm section, markedly suppressing distortion tendencies within pressure plate region so that it has dramatically bolstered equipment's operational stability, resilience, longevity, ensuring superior performance longevity. At same time, this scheme not only ensures newly added counterweight does excessively manufacturing costs but also takes account economic safety equipment. It serves as a valuable reference point enhancing efficiency production offering comprehensive blueprint future improvements.</div></div>

Transactions of the Canadian Society for Mechanical Engineering, Journal Year: 2024, Volume and Issue: 48(3), P. 369 - 392

Published: Sept. 1, 2024

To improve the static and dynamic performance of CNC machine tool tables, a multi-objective optimization design method based on bionic structures is proposed, which involves size design. Based bionics, four types structure tables for original XK5032 were designed, namely bamboo cross-section table, spider web honeycomb prairie rushes table. Static modal analysis conducted using finite element simulation methods validated through experiments. The results show that overall mechanics have been improved compared to Using entropy weight TOPSIS method, table was selected from tables. Conducting three candidate schemes obtained. entropy-weighted used again select optimal solution these schemes, resulting in 0.8% reduction mass, an increase first-order natural frequency by 2.8%, decrease maximum displacement 3.2%, significant 21.6% equivalent stress
