摘　　要：选取不同施工方案试制的ST235/80R16 10PR拖车轮胎,分别研究带束层胶片贴合方式、胎体帘布压延厚度、胎体帘线型号、胎体成型方式、三角胶高度及硫化条件等因素对其耐久性能的影响。结果表明:在硫化体系相同的前提下,低温硫化对轮胎耐久性能提升效果最为明显;在此硫化条件基础上,通过增大胎体强度,减少轮胎应力集中和降低生热,也可提升轮胎的耐久性能。ST235/80R1610PR trailer tires trial-produced with different construction schemes were selected to study the effects of the laminating method of the belt sheet,the calendering thickness of the carcass cord fabric,the type of carcass cord,the molding method of the carcass,the height of the apex and the vulcanization conditions,on the durability of the tires.The results showed that,with the same curing system,the tire durability was significantly improved by using low-temperature vulcanization process.In addition,under low-temperature vulcanization condition,the durability of the tire could also be improved by increasing the carcass strength,reducing stress concentration of the tire and reducing heat build-up.
