Abstract: The difference of the rolling resistance between the bench test and road test is analyzed, which verifies the feasibility of the test method on the rolling resistance. The rolling resistance is studied by MAHA four-drive chassis dynamometer based on the four design factors including environment temperature, inflation pressure, front wheel vertical load, velocity. An orthogonal test table with four levels and five factors is established to investigate the combined effects of the four factors on the rolling resistance based on the results from single factor analyses. The test results can instruct and provide evidence to vehicle performance test.
