Abstract:In this paper, the sliding constraint surfaces are automatically generated by a Pseudo-Minimum Area method (PMA), and the Initial Guess is generated on the constructed sliding constraint surface based on the One-step inverse approach. In the PMA method, the three-dimensional construction problem of sliding constraint surfaces was converted into a Quadratic Programming (QP) problem from the perspective of optimization. Since the high-efficiency solving of QP problems, the sliding constraint surfaces can be generated efficiently. Constructed sliding constraint surfaces and Initial guesses are applied to the multi-step drawing process. The numerical analysis result is compared with One-step inverse analysis and DYNAFORM to evaluate the effectiveness of the multi-step inverse analysis.
