摘　　要： 简要总结了中、高模量材料同冰雪之间的摩擦机理及相关理论,系统分析了影响冰雪路面上橡胶块和轮胎摩擦行为的因素;指出在一定工作条件下,轮胎性能和设计参数,包括胎面胶的低温模量、轮胎结构和胎面花纹等是影响轮胎摩擦牵引力的重要因素,其影响程度取决于运行条件;并就轮胎摩擦特性、全天候轮胎研制及轮胎力主动控制等方面的研究方向和热点提出了建议. The stateoftheart of friction study of some materials with medium or high values of elastic modulus used to make sledges and skates was summarized in connection with the friction mechanisms and theories. The factors affecting the friction or traction characteristics of the tires or rubber specimens on ice and snow were analyzed. It was shown that tire traction performance was, at given conditions, closely related to the tire tread properties such as low temperature modulus of the tread compounds and to the tire design such as the tire construction and tread patterns as well. The extent of such effects was dependent on the tire operating conditions and the environment. Some suggestions were presented for the future study of traction mechanisms, allseason tires development, and the active control techniques for tire traction.
