轿车副车架模态试验与分析

Model Test and Analysis of Secondary Car Frame

本文将现代测试手段和模态分析技术相结合,介绍了某轿车副车架的试验模态分析方法,采用白噪声 随机激励法进行了模态试验,并应用模态分析软件辨识其模态参数,为进一步的理论分析及改进结构设计提供了 指导。

Based on the combination of modern testing methods and modal analysis technology, this paper introduces the modal analysis and test of the secondary car frame and conducts lots of modal tests using the white noise methods. This paper also identifies the modal parameters using the modal analysis software and the results will help the further theory research and the modification of the structural design.
