| Abstract: | 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. |

| Keywords: | wheel radial fatigue testing machine drum test load test speed uncertainty |
