摘要
试验模态分析技术是获得结构动态特性的一种重要方法。将试验模态技术应用到某SRV车门的结构动态分析中,并通过对车门模态的振型分析,确定该车门模态的主要振型,从而通过改变车门的某些局部结构,降低局部振动,提高整车的NVH水平。
Experimental modal analysis is an important method for understanding the dynamic characteristic of construction. This paper introduces experimental modal analysis into the structure dynamic analysis of a SRV door,and the analysis results show the main modal frequency of the door. By adjusting the structure of the car door, the partial vibration is reduced and the NVH performance is improved.
