轮胎-地面静态接触的有限元分析

建立了一个钢丝增强橡胶轮胎结构伯有限元静态分析模型，并列举了３种不同粗细网网格（１６７，１８２和３１３节点）划分的实例。结果表明，用不同有限元网格计算的轮胎最大截面宽度、接地总反力及接地面积随下沉量变化的结果是一致的，因此可用较少的网格（如１６７节点）来完成相应的计算，并可达到预期的结果，轮胎接地压力分布、接地面积及形状丰趋势上与文献报道的一致，说明此模型有效可靠。

Analysis of static tire/ground contact with FEM

A model for statically analysing the steel reinforced tire with FEM was established and an example was given for three different network partitions (167,182 and 313 nodes).The results showed that the maximum cross sectional widths,the total reactions against the ground and the ground contact areas as the function of the deflections calculated with different FE networks were similar,therefore the corresponding calculation could be completed with less networks (for example 167 nodes) to obtain predicted results.The model was valid and reliable because the pressure distribution at the tire ground contact,the tire ground contact area and shape were in accordance with those reported in the previous papers.
