本文应用三向力传感器、轮胎变形传感器、车轮下陷传感器对车轮与地面间三向应力分布、轮胎变形规律进行了大量的试验研究。提出了二点新的假设为:1.把车轮与地面相互作用这一空间问题简化为平面问题来处理是有条件的;2.接触面上的法向应力可表示为相应点处轮胎变形的函数。在此基础上提出了牵引性能计算分析方法和原程序
In this paper, three-dimensional force sensors, tire deformation sensors, wheel sag sensors on the wheel and the ground three-dimensional stress distribution, tire deformation rules conducted a large number of experiments. Two new assumptions are proposed as follows: 1. It is conditional to simplify the problem that the interaction between wheel and ground is a plane problem; 2. The normal stress on the contact surface can be expressed as the deformation of the tire at the corresponding point function. On this basis, the traction performance calculation and analysis method and the original program are proposed
