THE INFLUENCE OF THE COEFFICIENT OF OVERTURNING-SIDE AND MATERIAL PARAMETERS ON THE PANEL OF AIR-CONDITION FORMING

By the finite element analysis software of DYNAFORM,the forming course of air-condition panel parts was simulated and analyzed. The effects rule of overturning-side coefficient for round hole and material parameter on maximal strain and thinning ratio were studied and analyzed during forming course,and the ralationship between turning-side coefficient and material parameters was established. It is very important to select the appropriate material in the forming of overturning side.
