Abstract：

Depending on the Draw Bead Simulator (DBS) tester, the influence of autosheets thickness on the frictional coefficient measurement was analyzed. The modified method to the formula was also suggested. The experimental result shows that the autosheets thickness makes the fixed draw bead specimens undertake different deforming force during forming process which influences the final coefficient of friction. It is better to remove such deforming force to test the coefficient of friction using DBS tester, and the comparison of the coefficient of friction between similar thickness sheets is more realistic in practice.
