摘要
分析电动汽车的各振动源,采用模态匹配策略和流程,制定模态频率规划表,在整车NVH虚拟设计平台上,对车身各部件的模态参数进行灵敏度分析和参数优化,得到较好效果。
The vibration source of electric vehicle is analyzed, and the modal matching strate- gy and process is adopted, and a planning table of modal frequency is developed. The sensitivity of the modal parameters of the body parts and parameter optimization are analyzed based on the vehicle NVH virtual design platform, and the result is effective.
