| 中文摘要: |
| 研究子午线轮胎滚动阻力试验结果可靠性。轮胎滚动阻力测试设备经过标定后的精度提高，通过实验室间滚动阻力系数平均值（Cr）比对，可满足滚动阻力测试精度要求；采用控制轮胎检测数据图进行分析和监控，当检测数据发生偏移时可及时判断引起检测数据偏移的原因；校正测量结果Cr与基准实验室之间直接比较的程序可将参比设备得到的结果转换成校正结果，保证了轮胎滚动阻力测试结果的准确性和可靠性。 |
| 英文摘要: |
| The reliability of radial tire rolling resistance test results was studied.After calibration，the accuracy of tire rolling resistance measurement equipment was improved，through the comparison of average value of rolling resistance coefficient（Cr） between laboratories，it could meet the requirements of rolling resistance test accuracy.The diagram of control tire test data was used for analysis and monitoring，when the test data was offset，the cause of the deviation of detection data was determined in time.The procedure of the direct comparison between the calibration measurement result Cr and the reference laboratory could convert the result obtained by the reference device into a calibration result，which could ensure the accuracy and reliability of tire rolling resistance test result. |
