摘要
以某轿车车身为研究对象,利用模态试验分析方法对该车身的疲劳破坏问题进行了解答。通过模态试验方法找到了前端模块振动破坏产生的根本原因,并根据数据,提出了改进措施。
In this paper,aiming at the car body,using the modal test analysis method,the reason for the fatigue destroy problem of body is resolved.Through the modal test,the root cause for the front module breakage is founded.According to the test data analysis,the improved measure is given finally.
