| 以规格为2.50－14的C形孔洞免充气轮胎为研究对象，基于Abaqus有限元分析软件，建立免充气轮胎三维有限元模型。针对免充气轮胎的支撑结构最大应力和接地面积，以孔洞圆弧半径、支撑结构数量、硬质弹性体层宽度和硬质弹性体层厚度4个因子进行正交试验分析。结果表明，孔洞圆弧内侧半径为17 mm和外侧半径为20 mm、支撑结构数量为40个、硬质弹性体层宽度为44 mm、硬质弹性体层厚度为6 mm的优化设计免充气轮胎的支撑结构性能、承载能力及接地性能提升较大。 |

| By using the finite element analysis software Abaqus，3-D finite element model of the nonpneumatic tire was established by taking 2.50－14 non-pneumatic tire with type C hole as the research object. Targeting the optimization of the maximum stress of supporting structure and grounding area of the non pneumatic tire，the orthogonal test was carried out to analyze four factors：the radius of the hole arc，the number of the supporting structure，the width of the hard elastomer layer and the thickness of the hard elastomer layer.The results showed that the supporting structure performance，load-carrying capacity and grounding performance of the non-pneumatic tire were greatly improved with the optimal design in which the inner radius and outer radius of the hole arc were 17 mm and 20 mm，respectively，the number of the supporting structures was 40，the width of the hard elastomer layer was 44 mm，and the thickness of the hard elastomer
layer was 6 mm. |
