摘要建立了恒速运行时达到热平衡状态的轮胎的能量损失与轮胎各组成部分的粘弹性之间的关系。通过系统地改变轮胎组件和操作参数，使用Vibron粘弹性仪和轮胎测试轮测力计进行分析。对6.95-14斜交轿车轮胎进行了研究。从导出的轮胎能量损失对粘弹性的依赖关系，可以预测轮胎胎面胶、帘布层橡胶和轮胎帘线的变化对轮胎能量损失的影响。这使得能够设计具有满足期望的服务特性的特性的轮胎。
Abstract A relationship between the observed energy losses for a tire that has reached a state of thermal equilibrium when operating at a constant speed, and the viscoelastic properties of the tire components has been formulated. The analysis was carried out by systematically varying tire components and operating parameters, using the Vibron Viscoelastometer and tire test wheel dynamometer. The investigation was carried out for 6.95–14 cross ply passenger tires. From the derived dependence of the tire energy losses on viscoelastic properties, the effect of changes in tire tread compound, ply rubber and tire cord on the tire energy losses can be predicted. This enables the design of a tire with the properties to meet desired service characteristics.
