To find parameters to estimate stamping formability of aluminum alloy sheet in autobody, simulate the cylinder components stamping process by LS-DYNA software based on dynamic explicit method; Study the impact of the material parameters (Yield stress RPS, hardening exponent n and anisotropy parameter r) and the process parameters (the blank-holding force and friction coefficient) on the stamping formability of the aluminum alloy sheet; Analyze the corresponding relationship between the research targets (material and process parameters) and the drawing properties through the Regression Analysis. The results indicate that the n values of the material parameters and all of the process parameters in this paper are remarkably correlated with the drawing properties of aluminum alloy, while the r values of the material parameters have little correlation with it.
