摘要:: 为进一步提高工程翻新轮胎的使用性能和奠定理论基础,以26.5R25全钢工程子午线翻新轮胎为研究对象,分析并设计了翻新轮胎的基本结构及尺寸,依据复合层型理论,构建了由胎面层厚壁圆筒模型、中垫胶层薄壁圆筒模型、带束层薄壁圆筒模型、胎体层薄壁壳体模型及胎侧层旋转圆环模型为主要构成的工程翻新轮胎多元复合层型,依据地面力学理论,采用极坐标的方式,分析和探讨了多元复合层型力学模型和细观静力学平衡方程的构建,描述了工程翻新轮胎各组成层的应力–应变关系矩阵.

Abstract:: 26.5R25 steel engineering meridian retreaded tire was regarded as study object,basic structurecomposition and dimension requirements of retreaded tires were analyzed and designed in order to lay the theo-retical toundation tor further improving use pertormance of engineering retreaded tures,engIneering retreadedtire multiple composite layer type mainly composed of tread layer thick-wall cylinder model,medium cushionrubber layer thin-wall cylinder model,belt layer thin-wall cylinder model,carcass layer thin-wall shell modeland tire side layer rotating ring model was constructed through theoretical analysis. Polar coordinate mode wasadopted for analyzing and discussing construction of multiple composite layer mechanical model and meso-stat-ics equilibrium equation based on ground mechanics theory.Stress-strain relation matrix of engineering retrea-ded tire tread rubber layer,buffer rubber layer,tire side layer,belt layer and carcass layer was described.
