摘　　要：在潮湿的天气或雨后，轮胎胎面或路面上存在一层很薄的水膜，该水膜使车辆行驶的牵引力降低。建立了轮胎胎面单元挤压膜问题的数学模型，并进行了数值求解，分析了胎面单元的几何参数、液膜厚度和柔性对轮胎薄膜湿牵引性能的影响，为轮胎胎面花纹的合理设计提供了理论依据。At dampy climate or after rain, there is a very thin water film on tyre tread or road surface, which causes motor vehicle tractive force reduction during driving. Mathematical model of compressed wet film on tyre tread element is established and numerical value salvation brought about. Effect of garetrical parameter on tyre tread element and also thickness and flexibility of wet film upon tractive characteristic of wet film covered tyre are analyzed. Therefore, theoretical basis is then provided for rational design of tyre tread pattern.
