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。

Abstract:

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 results.
