微型客车车架多目标拓扑优化
|
摘要
为了设计合理可靠的微型客车车架,应用折衷规划法建立以柔度最小和低阶固有频率最高为目标的多目标拓扑优化数学模型,基于固体各向同性材料惩罚模型进行优化。基于拓扑优化结果,构造微型客车车架的三维模型,并对车架进行静态和模态分析,确认车架满足工作性能要求,由此验证了微型客车车架多目标拓扑优化方法的合理性与可行性。
In order to design a reasonable and reliable minibus chassis, a mathematical model for multi-objective topological optimization with minimum flexibility and maximum low-order natural frequency as the objective was established by using the compromise programming method, which was optimized based on SIMP. Based on the results of topological optimization, the 3 D model of the minibus chassis was constructed, and the static and modal analysis of the chassis was carried out to confirm that the chassis could satisfy the performance requirements, thus the rationality and feasibility of multi-objective topological optimization method for the minibus chassis might be verified.
