载重子午线轮胎行驶时的接触压力分布和滚动阻力是轮胎结构的基本特性，对汽车转向性能具有重要影响。此前已发表了许多关于这些轮胎特性的理论和实验研究。然而，由于分析和试验方面的困难，轮胎使用性能与轮胎结构性能之间的关系还没有得到充分的阐明。本文建立了由复合带环、侧壁Voigt型粘弹性弹簧系统和胎面橡胶组成的弹簧支撑环模型，分析了轮胎在60 km/h速度下的一维接触压力分布，在橡胶阻尼系数适当取值时，预测的接触压力分布与实验结果吻合较好。这一研究证实，速度的增加导致了速度的降低。
Abstract The contact pressure distribution and the rolling resistance of a running radial tire under load are fundamental properties of the tire construction, important to the steering performance of automobiles, as is well known. Many theoretical and experimental studies have been previously published on these tire properties. However, the relationships between tire performances in service and tire structural properties have not been clarified sufficiently due to analytical and experimental difficulties. In this paper, establishing a spring support ring model made of a composite belt ring and a Voigt type viscoelastic spring system of the sidewall and the tread rubber, we analyze the one‐dimensional contact pressure distribution of a running tire at speeds of up to 60 km/h. The predicted distribution of the contact pressure under appropriate values of damping coefficients of rubber is shown to be in good agreement with experimental results. It is confirmed by this study that increasing velocity causes th...
