中文摘要:
      针对同品牌同规格不同胎体结构的两种轿车子午线轮胎开展耐撞击性能对比研究，分别选取5条轮胎进行室内摆锤冲击试验，对轮胎撞击动能和撞击后状态进行分析。结果表明：单层帘布高反包胎体结构轮胎撞击动能明显小于双层帘布低反包胎体结构轮胎，鼓包发生率更高，耐撞击性能明显较差；胎体结构对轮胎耐撞击性能具有重要影响。
英文摘要:
      A comparative study on the impact resistance of two kinds of passenger car radial tires with the same brand，same specification and different carcass structure was carried out. Five specimens of each kind of tire were selected for indoor pendulum impact test，and the impact kinetic energy and post impact state of the tire were analyzed. The results showed that the impact kinetic energy of the tire with a single ply cord and high turn-up carcass structure was significantly lower than that of the tire with a double ply cord and low turn-up carcass structure，the incidence of bulging was higher，and the impact resistance was obviously poor. The carcass structure had an important influence on the impact resistance of the tire.
