In this paper a SRV white-body test modal analysis was completed.According to the test result adjusting the local structure of the white-body,the inner noise and the NVH quality were improved.

• 将试验模态技术应用到某SRV白车身的结构动态分析中,并通过对白车身模态和车内噪声优势频率的关联分析,确定该白车身模态分布对车内噪声峰值的影响,从而通过改变白车身的某些局部结构,降低车内噪声峰值,提高整车NVH水平。
