摘要: 单轨车辆的走行部径向通过曲线时可以减小走行轮的磨耗和导向轮的载荷。以跨坐式单轨车辆辅助导向装置的几何关系和油气弹簧的力学特性为出发点,推导辅助导向装置产生力矩与转向架和车体之间摇头角度的解析关系。建立有辅助导向装置时车辆稳态曲线通过的力学模型,分析辅助导向装置能够使转向架在圆曲线上处于径向位置的条件,并利用多刚体动力学软件建立跨坐式单轨车辆的稳态曲线通过验证模型。通过理论分析和模型仿真计算发现,当合理油压弹簧预压力选择合适的数值时,辅助导向装置的输出力矩与二系悬挂的回转力矩相互抵消,走行部的摇头角接近零,能够使转向架在圆曲线上处于径向位置,并有效缓解走行轮与导向轮的磨耗。

Abstract: The wear of running wheel and the load of guide wheel can be reduced when the bogie of monorail vehicle passes through the curve at the radial position. Based on the geometric relationship of the auxiliary guiding device of the straddle-type monorail and the mechanical characteristics of the hydro-pneumatic Spring, the analytical relationship between the torque generated by the auxiliary guiding device and the yaw angle between the bogie and the vehicle body is derived. In addition, the mechanical model of vehicle steady-state curve passing with auxiliary steering device is established. The condition that the auxiliary steering device can make the bogie in the radial position on the circular curve is analyzed, and the verification model of straddle-type monorail vehicle is established by using multi-body dynamics software. The theoretical analysis and model simulation show that when the reasonable pre-pressure of the hydraulic spring is selected, the output moment of the auxiliary steering device and the rotation moment of the secondary suspension can be offset each other. At this time, the yaw angle of the running part is close to zero, and the bogie can be placed in the radial position on the circular curve.
