摘　　要：多边形磨损是汽车轮胎磨损研究中的一个新课题,具有重要的理论价值和研究意义。考虑轮胎接地磨擦的非线性特性,建立了基于LuGre摩擦模型的轮胎多边形磨损的动力学模型。通过仿真给出了能够引起自激振动的车速和轮胎初始前束角范围。这些结果为减小或消除轮胎的自激振动提供了理论依据。Polygonal wear of tire is a new subject of the tire Studies the wear study which has great theoretical value and research meaning.Considering the nonlinear characteristic of tire grounding friction,a dynamic model of tire polygonal wear is established based on lugre friction model.The ranges of speed and initial toe-in angle which can motivate self-excited vibration are given through simulation.The results provide a theoretic foundation to reduce or eliminate the tire self-excited vibration.
