摘要
创建组合工况,采用加速度加载的仿真方法,基于变密度法和“包裹面”方案对电动物流车蓄电池支架进行结构拓扑优化,并通过尺寸优化对支架进行轻量化设计,得到符合性能和轻量化要求的结构设计方案。仿真结果表明,优化后的蓄电池支架整体刚度提高了10.5%,总质量降低了29.2%.
A combination of working conditions was created, acceleration loading simulation method was used, based on the variable density method and"wrap surface" scheme, the structural topology of the battery rack of the electric logistics vehicle was optimized. The lightweight design of the bracket was carried out through size optimization to obtain a structural design solution that meets the performance and lightweight requirements. The simulation results show that the overall stiffness of the optimized battery holder is increased by 10.5%, and the total mass is reduced by 29.2%.
