Tyre Mechanics Model and Simulation Analysis of Rubber Tyre Light Rail Vehicle

介绍了胶轮轻轨车辆的轮胎分类及其构造。通过对轮胎的力学特性、轮胎力学模型的分析,运用"MF"模型在Simulink软件环境中建立了轮胎力学模型,并分别在转向、制动两种工况下对模型进行了仿真分析。阐述了轮胎侧偏角和纵向滑移率对轮胎力的影响。

this paper, the classification and structure of rub-ber tyre light rail vehicle are introduced. By analyzing the tyre mechanical properties and tyre mechanical model, a tyre mechanical model using “MF” model in Simulink cir-cumstance is established, and simulation analysis is carried out in two working conditions of swerving and braking. Fi- nally, the influences of tyre slip angle and longitudinal slip ratio are described.
