摘　　要：驾驶员坐在驾驶室中感知车辆的运动响应,驾驶室及其悬置机构是影响驾驶员驾乘感觉的重要环节。为实时模拟商用车驾驶室的运动,采用基于特性的建模方法,将驾驶室的运动解耦为低频面内Motion运动和高频面外Ride运动,并考虑驾驶室悬置机构的承载特性、RC/PC导向特性和K&C运动学特性,建立了商用车全浮式驾驶室模型。最后,将驾驶室模型嵌入到89DOF整车模型中,进行某款牵引车的仿真,并与场地试验结果进行对比,验证了模型的有效性。The driver perceives the vehicle’s motion response while sitting in the cab,and the cab and its suspension mechanism are essential factors affecting the driving sensation of the driver.For real-time simulation of the cab movement,a characteristics-based modelling technical route is adopted in this paper,in which the cab’s movement is decoupled into low-frequency in-plane Motion and high-frequency out-of-plane Ride,comprehensively considering the load-carrying properties,RC/PC properties and K&C properties of the cab suspension mechanism,and a full-floating cab model for the commercial vehicle is established.Finally,the cab model is embedded into the 89DOF truck model to simulate a tractor,and the model’s fidelity is verified by comparing it with the field test re-sults.
