摘要: 介绍了试验模态分析的基本理论,针对新开发的某微型轿车的白车身振动情况,基于试验对该车的动态特性 进行分析研究;通过道路振动试验、白车身模态试验,得到白车身的各阶频率和模态特性;针对分析得到的动态特 性方面可能存在的缺陷,结合白车身工作频率分析,提出工程改进意见,为设计人员改进结构提供了试验依据。

关键词: 微型轿车, 白车身, 模态分析

Abstract: The basic theory of experim ental modal analysis was introduced. Dynamic characteristics were studied based on the vibrations of a certain white-body mini car. Through experiments of vibration and mode experiments, different modal frequencies and modal characteristics of the car were acquired. Based on drawbacks in dynamic characteristics and working frequency of vehicles, suggestions were made for designers to improve mini-car structures

Key words: mini car, white body, modal analysis
