摘要:
通过修正材料插值模型和引入应力均方差作为性能收敛指标,改进了基于von Mises应力的双向渐进结构拓扑优化(Bi-directional Evolutionary Structural Optimization, BESO)方法,并结合Abaqus有限元软件及MATLAB语言编程实现了该算法;在此基础上,优化设计了集材绞盘机摩擦卷筒,得到不同材料体积分数、不同旋转周期数时,摩擦卷筒的最优拓扑结构,在减轻质量的同时,降低了应力集中水平。优化结果对实现集材绞盘机摩擦卷筒轻量化设计具有工程指导意义。
Abstract:
The previous bi-directional evolutional structural optimization (BESO) method based on von Mises stress was improved by modifying the material interpolation model and introducing the stress mean square error as the performance convergence index. The improved BESO algorithm was realized by combining finite element software Abaqus with programming language MATLAB. On this basis, the yarder friction roll was optimized and the optimal structural topologies were obtained under different material volume fractions and different numbers of rotation periods, for which the mass and the stress concentration level decreased simultaneously. Optimization results provide a significant engineering guide for realizing lightweight design of the yarder friction roll.
