摘要

建立了跨座式单轨车辆理论模型和动力学模型，分析了单轨车辆的运动状态特别是轮胎的受力情况。仿真结果表明，导向轮和稳定轮需要结合轮胎性能设置合理的预压力，以保证车辆的抗倾覆稳定性和运行安全性，并避免过大地增加车辆的运行阻力；通过对3种导向轮与稳定轮的布置方案进行对比分析可知，合理地设计导向轮与稳定轮的布置方案，可以改变构架的转动中心，优化车辆的侧滚刚度和摇头刚度，从而改善车辆的运动状态和动力学性能，减小走行轮的侧滚角和侧偏角以及导向轮与稳定轮的侧滚角，改善轮胎的受力状态，从而减少轮胎的磨耗。

Abstract

The theoretical model and dynamic simulation model of the straddle monorail were established, and the motion state of the monorail, especially the force of the tyre was analyzed. The simulation results showed that the guide wheel and the stability wheel need to be set pre-pressure to ensure the vehicle anti-overturning stability and the operation safety, and avoid excessively increasing the running resistance of the vehicle; with the comparative analysis of the arrangement of the three types of guide wheels and stabilizing wheels, it was shown that reasonable design of the layout scheme of guide wheel and stabilizing wheel can change the rotation center of the frame, optimize the roll stiffness and shaking head stiffness of the vehicle, thus improving the vehicle's motion state and dynamic performance, reducing the roll angle and sideslip angle of the running wheel, as well as the roll angle of the guide wheel and stability wheel, and improving the tyre's stress state to reduce tyre wear.
