摘　　要：系统介绍频率响应分析方法的基本理论,并通过MSC Nastran对侧碰传感器安装点进行频率响应分析,在初始设计结构不能满足要求的情况下,通过结构优化提高侧碰传感器局部安装点的模态频率,满足设计要求.该优化对结构动态特性的改进有重要指导意义.The basic theory of the frequency response analysis method is introduced. The frequency response of the side sensor fixing point is analyzed by MSC Nastran. Under the issue that the initial design does not meet the requirements, the modal frequency of local fixing point is improved to make it meet the design requirements by structure optimization. The structure optimization has important guiding significance for the optimization of the structural dynamic characteristics.
