轿车车身模态修改灵敏度计算分析

The Sensitivity Analysis of Car Body Modal Modification

本文进行了某承载式轿车车身结构的低价模态参数修改灵敏度分析及应用探讨,提出了车身基本抗扭承载区及空间基本抗弯盒的概念。

In this paper, the sensitivity analysis and its application of low-order modal parameter modification about a monocoque car body are studied. The concepts of basic torsionloading area and special bending bearing box are put forward.
