免充气轮胎与子午线轮胎的有限元分析对比

Comparison of Non-Pneumatic Tire and Radial Tire by Finite Element Simulation

采用Abaqus软件建立特殊结构的免充气轮胎三维有限元模型,对其静态加载和侧倾工况进行模拟,并将计算结果与同规格11.00R20载重子午线轮胎的实测数据进行对比分析。结果表明:静负荷工况下,两者的静刚度曲线基本吻合,下沉量和接地面积接近,免充气轮胎最大接地压力较小;侧倾工况下,两者的接地面积和静刚度曲线的变化趋势接近。免充气轮胎可以达到同规格子午线轮胎的性能要求。

By using Abaqus software,the three-dimensional finite element model of special structure non-pneumatic tire was established,its static loading and cornering state were then simulated,and the simulation results were compared with the experiment results of the same size 11.00R20 truck and bus radial tire.The results showed that,under the static loading state,the static stiffness curves were similar,the contact area and deformation were close,and the maximum contact pressure of non-pneumatic tire was smaller.Under cornering state,the variation trends of the contact area and static stiffness curve were similar.It could be concluded that the performance of the non-pneumatic tire could match with that of the same size radial tire.
