| 摘 要： | 对怠速状态下振动过大的客车进行现场振动测试及锤击模态实验，得到整车的振动频率成分及固有特性。通过振动分析得出影响该客车振动的主要因素是发动机转动传到底盘大梁的振动，与怠速车速密切相关。并对其底盘进行结构仿真分析，经过与模态测试对比，最终确定客车振动是怠速的工作频率与车辆底盘固有频率的耦合问题，通过改变底盘局部结构合理消除共振耦合现象。

| Abstract: | Aiming at the problem of large vibration in the idle state,the vibration testing and hammering modal experiment were done for 6830CR1 bus.The natural frequency and intrinsic characteristics of the entire bus were obtained.It is found that the main factor influencing the bus vibration is the vibration of chassis beam transmitted from the engine,and this factor is closely related with the idle speed.Through the structural simulation analysis of the chassis and comparison of the result with that of the modal t... |
