摘　　要：利用自建的试验系统，采用单向聚酯帘线／橡胶复合材料模拟汽车子午胎的胎体，研究了疲劳载荷下橡胶复合材料的变形和损伤累积特性，讨论了两种加载方式对疲劳性能的影响，结果表明：定载荷疲劳测试优于定伸长疲劳测试．为评价轮胎的疲劳特性、预报轮胎的疲劳寿命提供了有效手段．A fatigue testing system for cord/rubber composites was established. Using this system, damage accumulation process and deformation under fatigue loading were assessed in the case of polyester cord reinforced rubber composite which represented the actual carcass of radial tires. The effect of fatigue testing methods on the fatigue properties of rubber composites was examined. The results indicated that constant load fatigue testing method is better than constant extension fatigue testing method. A method available for evaluating the fatigue behavior of tires and predicting the fatigue lifetime of tires was offered.
