提出了区域灵敏度分析方法，并通过设定关键区域的区域厚度变量，将灵敏度分析对象由单个零件的厚度变成关键区域的区域厚度变量。提出了基于优化空间重组及灵敏度筛选机制的空间多层形貌优化技术，对零件沿法向正反两个方向进行了结构形貌优化，并将两种方法应用到某车身轻量化设计中。应用实例表明，该方法可以成功地实现关键区域的灵敏度分析，并能大大缩短车辆开发时间优化。

This paper put forward the method of regional sensitivity analysis,by setting thickness-variables of the key regions as variables instead of single component thickness.And the paper also put forward the optimization technique of the space-multi-layer topography that was based on the recon-struction of the optimization space and the screening mechanism of sensitivity,which validly solved the optimizations problem of reinforcing plate to bulge from two normal sides of the plate.The two methods were applied to the lightweight of body in white(BIW)at the same time.The example indi-cates that the analysis method can analyze and solve the problem of regional sensitivity analysis suc-cessfully,and greatly shortenes vehicle’s development period.
