摘要

摘要: 应用有限元分析理论和Optistruct软件对某摩托车典型零部件-坐垫底板进行了刚度、频率等分析,得到了坐垫底板地变形分布图,应力分布图以及模型的低阶振频。利用拓扑优化和形貌优化相结合的优化方法,分别就柔度、频率为目标进行结构优化;针对单目标优化中出现的不足,提出了多目标优化方案,得到了优化模型,并与原方案和单目标优化方案进行对比分析。结果表明:多目标优化方案不但减少产品质量10%,柔度减少60%,且频率大大优于原方案和单目标方案。

Abstract: Applying the theory of FEA(Finite Element Analysis) and Optistuct software,the paper analyzed the stiffness and frequency of the support base of a motorcycle seat to get the deformation distribution,stress distribution and lower modal frequencies. Based on the analyzing results,an optimization approach combining topological optimization and topography optimization is adopted to conduct structure optimization by taking flexibility and frequency as the optimization objective respectively; then aiming at the insufficiency in single objective optimization, a multi-objective optimization scheme is proposed with comprehensive consideration; a optimization model is acquired and compared with the original scheme and the single objective optimization scheme.The results indicate that the multi-objective optimization scheme not only reduces 10% of product weight and 60% of flexibility,saves the cost with 1 Yuan RMB,but also the comprehensive performances such as frequency are much more optimized than the original one and single objective one.
