摘要
简述了有限元模态分析的基本理论,建立了某车身的有限元模型,并对其进行了模态分析,得到了车体的特征模型和固有频率。这对车身的结构改进及其安全性、稳定性、舒适性的提高,提供了依据。
The basic theory of finite element modal analysis is discussed briefly in this paper.and a vehicle body of finite element model and modal was estabcished analysis the model.Get the body characteristics of model and natural frequency.can be got.was made.This can provide a scientific reference and a basis to improve the structure of the body,the security,stability and the comfort.
