摘　　要：对车轮径向疲劳试验机转鼓、试验负荷和试验速度进行校准,并对试负荷和试验速度的不确定度进行评定。试验负荷和试验速度校准结果不确定度的要来源为试验机分辨力引入的不确定度、试验机测试重复性引入的不确定度、标测力仪或标准转速表分辨力引入的不确定度。The wheel radial fatigue testing machine was calibrated, including the drum, test load and test speed. The measurement uncertainties of test load and test speed were assessed. The main source of the measurement uncertainty was from the resolution and repeatability of the testing machine, and the resolution of force measurement sensor and tachometer.
