| 中文摘要: |
| 选取5家轮胎试验场进行轮胎湿路面相对抓着性能的试验场间比对试验，对试验结果进行系统分析与评价。结果表明：在相同轮胎、统一标准、统一测试条件下，5家轮胎试验场对6个品牌轿车轮胎的湿路面相对抓着性能测试结果的可比性较强；不同轮胎试验场的试验数据存在一定的数值偏差，T5轮胎试验数据的标准偏差最小，为0.022，一致性最好，T2轮胎试验数据的标准偏差最大，为0.052，一致性较差；路面构造深度、试验车型与负荷、环境温度及人员因素是轮胎试验场间试验数据差异的主要影响因素。为进一步提高国内不同轮胎试验场间湿路面相对抓着性能测试结果的可比性与一致性，建议持续推动试验标准与试验条件的高度统一，并定期开展各轮胎试验场间的试验能力比对工作。 |
| 英文摘要: |
| Five tire test facilities were selected to conduct inter-facility comparative tests on the relative wet grip performance of tires and the test results were systematically analyzed and evaluated.The results showed that using identical tires，unified standards and consistent testing conditions，the relative wet grip performance test results for six passenger car tire brands exhibited strong comparability across the five facilities.However，numerical deviations were observed among the test data from different facilities，with T5 tire showing the smallest standard deviation of 0.022 and the best consistency，while T2 tire exhibited the largest standard deviation of 0.052 and poorer consistency.Road texture depth，test vehicle type and load，ambient temperature and personnel factors were the primary contributors to differences in test data among tire testing facilities.To further enhance the comparability and consistency of wet grip performance test results among domestic tire testing facilities，it was recommended to continuously promote the strict standardization of testing criteria and conditions and to regularly conduct inter-facility testing capability comparisons. |
