基于侧向变刚度的轮胎多边形磨损机理分析（Mechanism of Polygonal Wear of Tire Based on Variable Stiffness of Lateral）
车辆 轮胎 多边形磨损 变刚度 机理
2010/12/29
考虑轮胎接地摩擦的非线性特性，建立了基于侧向变刚度的轮胎多边形磨损模型，并对系统的稳定性进行了分析，指出轮胎的自激振动是一种由系统Hopf分岔引起的稳定周期振动现象，通过数值仿真得到了引起胎面自激振动的车速和车轮前束角范围。结果表明：轮胎多边形磨损为一种典型的非线性自激振动现象，其发生与胎面的侧向振动有关，磨损边数近似等于胎面的侧向振动频率与车轮转动频率之比。所建模型能够很好地解释轮胎多边形磨损的...
