摘 要: 轮胎与路面接触面荷载呈现非均匀性分布,而当前路面结构设计采用双圆均布荷载的分布形式,与实际不符。采用ABAQUS有限元仿真软件,建立P215/70R15型子午线轮胎与刚性路面的接触作用模型进行仿真分析。结果表明:轮胎-刚性路面竖向接触应力分布并不均匀,应力区域近似椭圆状;轮胎接地面中心点和平均面竖向接触应力与充气压力、轮载呈正相关非线性变化,接地面最大竖向接触应力随充气压力增加表现为先降低后增大趋势,且最大竖向接触应力发生在胎冠边缘附近;轮胎最大竖向变形随充气压力增大而减小,随施加的轮载变化呈正相关线性变化。
关 键 词: 道路工程;接触作用;有限元仿真;竖向变形;充气压力

Abstract: The load distribution on the contact surface of tire and pavement is non-uniform, but the current pavement structure design adopts the double circle uniform load distribution form, which is not consistent with the actual situation. The contact action model of P215/70R15 radial tire and rigid pavement was established by using ABAQUS finite element simulation software. The results show that the vertical contact stress distribution of tire-rigid pavement is not uniform, the stress area is approximately elliptical. The vertical contact stress of center point and average plane on tire contact surface is positively related to the inflation pressure and wheel load, the maximum vertical contact stress on tire contact surface first decreases and then increases with the increase of the inflation pressure, and the maximum vertical contact stress occurs near the edge of the tire crown. Moreover, the maximum vertical deformation of tire decreases with the increase of the inflation pressure, and presents a positive linear correlation with the variation of wheel load.
Key words: road engineering; contact action; finite element simulation; vertical deformation; inflation pressure
