摘要
通过声振实验测量了燃料电池轿车不同匀速行驶工况下的车内噪声和主要零部件的振动状况,实验结果表明高速工况下驱动电机单元成为车内噪声的主要来源。并在ADAMS中建立了驱动电机与副车架刚柔耦合振动仿真模型,分析了柔性副车架对振动系统模态的影响。
Through a fuel cell car vibro-acoustic experiment the interior noise and some components＇ vibration levels in different operating condition are measured. The results show that while the traction motor＇s contribution to the interior noise becomes more dominated with the increase of the vehicle＇s speed. The driving motor and subframe coupling dynamic model is established in ADAMS, the mode of the mount system with rigid and flexible subframe are calculated. The results show that the modal frequency of the mount system will be reduced if the subframe is elastic.
