The stamping process of concave part was simulated by software Dynaform, and the influences of process parameters on forming effect of part were studied. Based on the orthogonal test, taking the minimum and the maximum wall thicknesses in the concave position of part as evaluation indexes, the influences of outer corner, sidewall length, internal corner, drawing height, stamping speed, blank holder force and friction coefficient on the wall thickness were studied, and the optimum combination of forming process parameters was obtained. The simulation results show that the optimum wall thickness in the concave position of part is obtained with the outer corner R1=10 mm, the sidewall length l=6 mm, the internal corner R2=10 mm, the drawing height h=25 mm, the stamping speed v=1000 mm·s-1, the blank holder force F =7.5 kN and the friction coefficient μ=0.1, and the verification test was conducted by the optimum process parameters. Furthermore, the results of drawing test and simulation are compared, and the wall thickness distributions in the concave position of part are consistent.
