摘　　要：从轮胎结构入手,采用单一变量控制法,研究三角胶高度、三角胶硬度、胎体帘布层数、胎体帘布反包高度及冠带条缠绕方式对285/35ZR22 106XL/W低扁平比轿车子午线轮胎耐久性能的影响。结果表明:在一定范围内,三角胶高度和三角胶硬度越小,轮胎低气压耐久性能越好;与胎体采用单层2200dtex/3聚酯帘布的轮胎相比,胎体采用双层1100dtex/2聚酯帘布的轮胎低气压耐久性能更优;与胎体帘布反包至三角胶上方10 mm的轮胎相比,胎体帘布反包至带束层底部的轮胎低气压耐久性能更优;与1.5层冠带条缠绕轮胎相比,2层冠带条缠绕的轮胎低气压耐久性能更优。Starting from the tire structure,the effects of the apex height,apex hardness,carcass ply number,carcass ply turn up height and crown strip winding mode on the low-pressure durability of the 285/35ZR22 106XL/W passenger car radial tire with low aspect ratio were studied by single variable control method. The results showed that in a certain range,the smaller the apex height and the apex hardness were,the better low pressure durability of the tire was. Compared with the tire with a single-layer of 2200dtex/3 polyester fabric,the tire with a double-layer of 1100dtex/2 polyester fabric had better low pressure durability.In addition,compared with tires with carcass plies turned up to 10 mm above the apex,tires with carcass plies turned up to the bottom of the belt had better low pressure durability. Compared with tire with 1. 5-ply crown strip winding,the tire with 2-ply crown strip winding had better low pressure durability.
