动力总成悬置系统隔振原理分析及振动解决措施

Analysis of vibration isolation principle of powertrain mounting system and vibration solution of mounting system

针对动力总成悬置系统对整车振动及乘员舒适性的影响,对悬置系统隔振原理进行分析。根据隔振原理,对某MPV全油门工况下轰鸣问题进行排查,对悬置系统结构进行优化,从而提高了整车的NVH性能。

In the light of the influence of powertrain mounting system on vibration and occupant comfort,the vibrationisolation principle of mounting system is analyzed.According to the principle of vibration isolation,the problem of the roarof a full throttle of MPV is investigated,and the structure of the munting system is optimized,so as to improve the NVHperformance of the vehicle.
