摘　　要：在考虑车架弹性的基础上研究了全浮式驾驶室悬置隔振问题,建立了整车刚柔多体参数化模型,并进行了仿真。分析了不同车架柔性对全浮式驾驶室平顺性的影响。结果表明,车架的固有频率、相应振型对全浮式驾驶室平顺性均有影响,如果车架第1阶固有频率小于10Hz或者更低,则平顺性变差。The vibration isolating suspension of the full-float cab in commercial vehicle has been studied based on the frame flexibility. The rigid-flexible multi-bociy vehicle vibration simulation model including the flex frame was used in simulation with ADAMS and ANSYS software. Furthermore, the ride comfort of full-float cab in a whole commercial vehicle was studied by changing the flexibilities of frame. The results showed that the ride comfort of full-float cab depended on the natural frequency and corresponding vibration mode of the frame, the ride comfort of full-float cab would become terrible if the first natural frequency of frame was less than 10 Hz or lower. It offered a valuable method to the match of the full-float vehicle parameter and the design of frame.
