摘要
白车身关键安装点的动刚度性能将直接影响整车的NVH性能,通过对白车身相关安装点进行频响分析,能够保证整车的NVH性能,缩短整车开发周期节约成本。以某款公路客车白车身为研究对象,建立白车身的CAE模型,运用其中的Hypermesh模块,对白车身的前后悬架接附点进行模态频率响应分析。通过分析结果,发现前后悬架在设计上的缺陷,并提出改进意见,保证了整车的NVH性能。
The dynamic stiffness performance of the key installation points of the body-in-white will directly affect the NVH performance of the vehicle. By analyzing the frequency response of the relevant installation points of the body-in-white, the NVH performance of the vehicle can be guaranteed, the development cycle can be shortened and the cost can be saved. Taking the white body of a highway bus as the research object, the CAE model of the body-in-white is established, and the Hypermesh module is used to analyze the modal frequency response of the front and rear suspension attachment points of the white body. Through the analysis of the results, the defects of the front and rear suspensions were found, and suggestions for improvement were made to ensure the NVH performance of the vehicle.
