Abstract: The sinking-resistance is one of the important performance properties of automo bile panel. The evaluation methods of sinking-resistance for auto-body sheet w ere proposed and some key factors were introduced, which include test principle, shapes/status of specimens as well as evaluating parameters of test r esults.The special test machine for evaluating sinking-resistanc e was developed, which is controlled by micro-computer. Its struc ture, measurement and control system as well as loading system were described. The application in the factory indicates that the test results are stable and relia ble.
