Abstract: The rolling resistance of a pneumatic tire primarily depends on the deformation of the circumference between the tire and ground. There are three elements effecting the circumference: P_i, the inflation pressure of the tire; P_C, the pressure due to carcass stiffness and the specific pressure q that deformable ground can support. Based on all these situations of the circumference, this paper discusses the parameters which influences the rolling resistance and points out the methods for decreasing the rolling resistance in detail.

摘要： 运行中的轮式越野车辆,其滚动阻力主要取决于轮胎与地面间支承面的形状。影响此支承面形状的因素有三:轮胎充气压力P_i,胎壁刚度换算压力P_C和松软地面可能提供的接地比压q。基于支承面可能有的三种变化情况,本文探讨了影响滚动阻力的各项参数并指明了降低它的具体方法。
