摘　　要：针对车辆轻量化设计出现的门下垂的问题,提出了分析方法和判断标准。以某款轻量化设计的轿车出现抗下垂性能降低的问题为例,提出了优化小板件厚度并结合灵敏度方法来补偿性能的降低,对优化后结构分析显示侧门的抗下垂性能得到改善,并保证了改进结构的质量增加为最小。For the problem to side door sag after light-weight design, analysis method and criterion are introduced. Take a light-weight design sedan＇ s problem to side door sag as on example, and introduce optimization analysis method considering the sensitivity analysis to improve it. The analysis result of improvement shows that the capability of side door sag is enhanced and the addition mass is the minimal.

关 键 词：门下垂性 最大变形量 残余变形 优化分析 灵敏性分析
