摘　　要：以12R22.5全钢载重子午线轮胎为例,采用有限元分析软件建立轮胎的三维有限元模型,仿真分析静态加载、制动和驱动状态下轮胎的接地印痕。结果表明:自由滚动状态下轮胎的接地印痕面积小于静态加载状态下轮胎的接地印痕面积,且自由滚动状态下轮胎的接地印痕压力区域更为集中,接地印痕压力的最大值大于静态加载状态下轮胎的接地印痕压力的最大值;自由滚动状态下,随着行驶速度的增大,轮胎的接地印痕面积逐渐减小,接地印痕压力逐渐增大;制动状态下,轮胎的接地印痕前端的接地面积小于后端的接地面积,而接地印痕前端的压力大于后端的压力;驱动状态下,轮胎的接地印痕前端凸出,后端趋近为水平线,而接地印痕前端的压力小于后端的压力。Taking the 12R22.5 truck and bus radial tire as an example,a three-dimensional finite element model of the tire was established using finite element analysis software to simulate and analyze the footprint of the tire under static loading,braking and driving states.The results showed that the footprint area of the tire under the free rolling state was smaller than that under the static loading state,and the footprint pressure region of the tire under the free rolling state was more concentrated,with the footprint pressure maximum value of the tire greater than that under the static loading state.Under the free-rolling state,as the driving speed increases,the footprint area of the tire gradually decreased,and the footprint pressure gradually increased.Under the braking state,the contact area at the front end of the footprint of the tire was smaller than that at the rear end,and the pressure at the front end of the footprint was greater than that at the rear end.Under the driving state,the front end of the footprint of the tire protruded,the rear end approached a horizontal line,and the pressure at the front end of the footprint was larger than that at the rear end.
