基于Nastran的某SUV白车身NVH性能仿真研究

Simulation Research on NVH Performance of a SUV BIW based on Nastran

白车身是SUV重要组成部分,对整车性能有重要影响,文章针对某SUV车型白车身进行了CAE模态和刚度及NTF分析,结果表明,此SUV白车身NVH性能满足目标要求。

BIW(body in white)is an important part of SUV,which has an important impact on the performance of the whole vehicle.In this paper,CAE modal analysis,stiffness analysis and NTF analysis are carried out for BIW of a SUV.The results show that the NVH performance of BIW meets the target requirements.
