基于灵敏度和碰撞仿真的汽车车身轻量化优化设计（Lightweight Optimization Design of Car Body Based on Sensitivity and Side Crash Simulation）
汽车 车身 轻量化 灵敏度
2010/12/29
提出了基于灵敏度分析和侧面碰撞的汽车车身结构轻量化设计方法。首先以车身结构零件的板厚为设计变量，以白车身的模态和刚度为约束条件，白车身质量最小为目标，分析了零件板厚关于车身模态和刚度的灵敏度。选取对车身模态和刚度以及抗撞性不敏感的车身零件的板厚，进行以白车身质量最小为目标的优化计算。优化结果使车身减轻14.8 kg。对轻量化后的整车和乘员约束系统进行了侧面碰撞的模拟计算，并与轻量化前的结果进行了对...
