Lightweight Optimization Design of Aluminum Electric Vehicle Body Based on HAM in Concept Design Phase of Development

  • 摘要: 在汽车车身概念设计阶段,针对轻量化设计及优化白车身刚度问题,建立了某款纯电动铝合金汽车车身骨架基于真实接头的简化力学模型。运用灵敏度分析筛选出灵敏度较大部件,然后利用元模型的优化方法(hybrid and adaptive meta-modeling method,HAM)对灵敏度较大部件进行截面厚度优化,使优化目标车身质量得到了降低,同时改善了车身的模态和刚度,根据研究的数据制造了电动车车身。
