摘　　要：介绍半钢轻型载重子午线轮胎的施工优化。骨架材料采用新型高强度3+8×0. 23ST钢丝帘线代替2+7×0. 28HT钢丝帘线,通过改进胎侧和三角胶设计转移生热位置。成品性能测试结果表明,优化后轮胎的充气外缘尺寸、强度性能、脱圈阻力、高速性能、耐久性能、低气压耐久性能以及滚动阻力满足FMVSS,ECE或ISO相关标准要求,优化后轮胎的高速性能和耐久性能明显提高,滚动阻力减小。The construction optimization of steel-belted light truck radial tires was introduced. Instead of 2+7×0. 28 HT steel cord,new high strength 3+8×0. 23 ST steel cord was used as the skeleton material.The design of the sidewall and apex was improved and the heat generation position was transferred. It was confirmed by the finished tire test that,the inflated peripheral dimension,strength,bead unseating resistance,high speed performance,durability,low inflation pressure durability and rolling resistance of the tire met the requirements of FMVSS,ECE or ISO related standards. The high speed performance and durability of the optimized tire were improved significantly,and the rolling resistance was reduced.
