Die-face Optimization Design and Forming Simulation of Cover Plate Brace Wheel Housing

Based on the design principles and methods of addendum,binder surface and bead of automotive panel,the drawing model of cover plate brace wheel housing was designed.Using FEM software Dynaform,the process of the drawing was analyzed.Based on the simulation results,the drawing surface was optimized.To change the flat parting surface into curred face,and change the rectilinear bead into pitch arc,the disfigurement occurring in the forming of drawing part was ultimately eliminated.The eligible drawing part was gained.
