骨架材料对免充气轮胎承载性能和接地性能的影响

本研究以规格为2.50-14的C形孔洞免充气轮胎为例，基于Abaqus有限元分析软件，建立免充气轮胎的三维有限元模型，针对接地应力分布不均的问题，嵌入不同宽度和厚度的高苯乙烯硬质弹性体层作为骨架材料，对免充气轮胎的承载性能和接地性能进行优化分析，得到硬质弹性体层的最优厚度和宽度。结果表明，硬质弹性体层宽度为40 mm、厚度为6 mm时免充气轮胎的承载性能和接地性能较好。;Based on the Abaqus finite element analysis software，the three-dimensional finite element model of the C-hole non pneumatic tire with a specification of 2.50-14 was established in this study.Aiming at the problem of the uneven distribution of the ground stress，a high styrene hard elastomer layer with different width and thickness was embedded as the skeleton material.The bearing capacity and grounding performance of the non pneumatic tire were optimized，and the optimum thickness and width of the hard elastomer layer were obtained.The results showed that when the width of the hard elastomer layer was 40 mm and the thickness was 6 mm，the bearing capacity and grounding performance of the tire were better
