研究车轮——地面接触面间应力和应变关系,是汽车——地面力学重要内容之一。为此,各国学者相继作了很多的努力,但到目前为止,尚未建立完善的理论。本文通过试验的方法,着重研究了BJ—212轻型越野汽车的两种轮胎,在各种不同情况下的法向应力的分布和数值,进行了载荷,轮胎气压和工况对轮胎——地面接触面间法向应力影响的初步分析。并在此基础上,同时研究了BJ—212轻型越野汽车的轮胎刚度和气压对行驶阻力的影响,对该汽车轮胎的合理选择提出了初步意见。
Studying the relationship between stress and strain at wheel-ground contact surface is one of the most important contents of automotive-ground mechanics. To this end, scholars from various countries have made a lot of efforts one after another, but so far no sound theory has been established. In this paper, the test method focuses on the distribution and values of normal stress in two kinds of tires of BJ-212 light off-road vehicle under various conditions. The load, tire pressure and working conditions on tire-surface contact A Preliminary Analysis of the Effect of Normal Stress Between Surfaces. Based on this, the influences of tire stiffness and air pressure on driving resistance of BJ-212 light off-road vehicle are also studied, and preliminary opinions on the reasonable choice of the tire are proposed.
