| 中文摘要: |
| 对轮胎强度试验的不确定度进行评定。轮胎强度试验的不确定度来源为作用力和行程位移。作用力测量不确定度包括试验机作用力示值分辨力引入的标准不确定度、作用力校准引入的标准不确定度和作用力测量重复性引入的标准不确定度。行程位移测量不确定度包括试验机行程位移示值分辨力引入的标准不确定度、行程位移校准引入的标准不确定度和行程位移测量重复性引入的标准不确定度。 |
| 英文摘要: |
| In this study，the uncertainty of the tire strength test was evaluated. The uncertainty of the tire strength test was mainly from the force measurement and stroke displacement measurement. The uncertainty of the force measurement included the standard uncertainty introduced by the resolution of the test machine， the standard uncertainty introduced by the force calibration，and the standard uncertainty introduced by the repeatability of force measurement. The stroke displacement measurement uncertainty included the standard uncertainty introduced by the resolution of the test machine，the standard uncertainty introduced by the stroke displacement calibration，and the standard uncertainty of the repeatability of stroke displacement measurement. |
