摘要
采用ABAQUS有限元分析软件,以11.00R20充气子午线轮胎为参考,建立了两种结构的免充气轮胎三维模型,分别对其标准工况下的静态加载过程进行了模拟。结果表明,菱形孔结构和交错结构支撑体免充气轮胎静载荷刚度曲线、轮胎接地面积、平均接地压力与充气轮胎实测值比较接近,可以满足同种规格充气轮胎的使用性能;最大接地压力小于充气轮胎实测值,可以减轻轮胎的不均匀磨耗问题;交错结构支撑体免充气轮胎的行驶稳定性明显优于菱形结构支撑体免充气轮胎。
Based on the size 11.00R20 pneumatic radial tire,two kinds of three-dimensional nonpneumatic tire models were established by using of ABAQUS software,its static loading under normal working conditions was then simulated.The results showed that the static stiffness curves, the contact area and the average contact pressure of the rhombohedral hole structure and the staggered structure supports non-pneumatic tire were close to the measured value of pneumatic tire.So the performance of the non-pneumatic tire may match with that of the same size pneumatic radial tire.The maximum contact pressure of the non-pneumatic tire was less than that of the pneumatic tire, which can reduce the uneven tread wear phenomenon. Steering stability of the staggered structure non-pneumatic tire was significantly outperformed the rhombohedral hole structure non-pneumatic tire.
