摘要
提出一种交错结构免充气安全轮胎,借助有限元分析软件Abaqus对其静态接地性能进行分析,并采用德莫西亚疲劳试验获得轮胎支撑体聚氨酯材料的应力(S)-疲劳寿命(N)曲线,将其输入疲劳分析软件FE-SAFE预测轮胎的疲劳寿命。结果表明,交错结构免充气轮胎的静刚度曲线与同规格充气子午线轮胎基本吻合,接地面积和平均接地压力接近,说明其达到了同规格充气子午线轮胎的使用性能,且疲劳寿命相近。
A staggered structure non-pneumatic safety tire was proposed,and its static grounding performance was analyzed by finite element analysis software Abaqus. The stress(S)-fatigue life(N)curve of polyurethane support material of the tire was measured by Demencia fatigue test and imported to fatigue analysis software FE-SAFE to predict the fatigue life of the tire. The results showed that,the static stiffness curve of the tire was consistent with that of the pneumatic radial tire with the same size,the contact area and average contact pressure were similar,which indicated that the tire had reached the service performance of the same size pneumatic radial tire,and the fatigue life was similar.
