Analysis of test method of vehicle tire rolling resistance tester

In order to evaluate the feasibility of test scheme for vehicle tire rolling resistance, based on tire rolling resistance measurement system model, a new method of studying tire rolling resistance was developed with displacement deformation. Based on brief introduction of construction process of finite element test model for rolling resistance, by controlling the experimental parameter of outer tire, the displacement field distributions of sensor plate were studied under different conditions and test scheme was worked out. Regarding the sensor installation positions as the detection points, the relation curves between tire rolling resistances and the control parameters were established. After average filtering treatment of collected data, calculated values were compared with test data. Results show that tire rolling resistance rises as the load or speed enhances and reduces as the pneumatic pressure increases. The simulation results are consistent with test data. It is validated that the proposed test method is reasonable and feasible.
