| Abstract: | This paper introduced car suspension tester, wheel ground adhesion index and its evaluation criteria. The analytical formula for the wheel ground adhesion index is given. The influence of tire stiffness,damper efficiency and ratio of sprung to unsprung mass on the index is simulated. The results show that the suspension test is a necessary measure to ensure the car running and driving safety. |
