  • To ensure test data precision for rolling resistance, the key factors affecting equipment performance were assessed and predicted. Based on the equipment measuring principle, numerical simulation model for tire rolling resistance was established. Physical output quantity of sensor was collected and processed. Furthermore, rolling resistance test properties were obtained by finite element analysis. The difference in test data was contrasted by changing the relative reference position between the drum and the axle. Linear regression orthogonal was adopted for error-correction. Compared with the laboratory data, trend test shows that the test model can reflect the response relationship between rolling resistance and controlling parameters, so the test model has high reliability. The replicate test shows that the error-correction model for rolling resistance can reduce the equipment system error and improve the measurement accuracy. The simulation results provide practical basis for equipment development.
