| 中文摘要: |
| 基于现行双胎法轮胎耐撞击性能标准试验方法，研究轿车轮胎摆锤法耐撞击性能试验影响因素。结果表明：轮胎个体的耐撞击性能测试结果存在一定的差异，鼓包破坏能平均差为62.9 J；轮胎不同位置及累积撞击造成的鼓包破坏能测试结果平均差为37.1 J；轮胎充气压力越大，耐撞击性能越好，但不同轮胎的耐撞击性能随充气压力变化的趋势不同；轮胎与摆锤的撞击外倾角越大，轮胎越容易鼓包；悬挂摆锤接触轮胎与接触轮辋的耐撞击性能测试结果没有显著差异，但摆锤中心对胎肩与对胎面中心测试结果差异显著。 |
| 英文摘要: |
| Based on the current impact resistance test standard method of twin tire method，the influencing factors of impact resistance test of passenger car tire by pendulum method were studied.The results showed that there was a certain difference in the impact resistance test results of individual tires，and the average difference of bulge destructive energy was 62.9 J.The average difference of bulge destructive energy test results caused by different tire positions and cumulative impact was 37.1 J.The higher the inflation pressure of tire was，the better the impact resistance was，but the trend of change of impact resistance with the inflation pressure of different tires were different.The greater the impact camber angle between the tire and the pendulum was，the easier the tire was to bulge.There was no significant difference in the test result of impact resistance between free suspension pendulum contact tire and rim contact tire，but the difference of test results between pendulum center to shoulder and tread center was significant. |
