| 中文摘要: |
| 根据静负荷性能试验数据，利用软件插值计算出缺气保用轮胎在不同负荷下所允许使用的最小安全充气压力。试验测得，225/55ZRF17 97W标准型和225/55ZRF17 101W增强型缺气保用轮胎在各自标准充气压力和标准负荷下的标准下沉量分别为26.07和21.15 mm。软件计算分析表明，在标准下沉量下，单胎负荷为455 kg时，225/55ZRF17 97W标准型和225/55ZRF17 101W增强型缺气保用轮胎允许使用的最小安全充气压力分别为112和54 kPa。汽车更换不同品牌的缺气保用轮胎时，应重新计算轮胎的最小安全充气压力，校正胎压监测报警系统。 |

| According to the static load performance test data，the minimum safe inflating pressure of run-flat tire under different loads was calculated by software interpolation.The test measuremented that the standard sinkages of 225/55ZRF1797W standard and 225/55ZRF17 101W enhanced run-flat tire were 26.07 and 21.15 mm respectively under their respective standard inflating pressures and standard loads.Analysis of software calculation showed that under the the standard sinkages，the minimum safe inflating pressures of 225/55ZRF1797W standard and 225/55ZRF17 101W enhanced run-flat tire were 112 and 54 kPa respectively when the single tire load was 455 kg.The minimum safe inflation pressure of tires should be recalculated and the tire pressure monitoring and alarming system should be corrected when replacing different brands of insured tires. |
