| Abstract: | Hydrodynamic deep drawing（HDD） is a kind of advanced sheet metal forming method. Satisfying the need of adornmenl parts and aiming at paraboloid chimney HDD was studied by means of numerical simulation. The dynamic explicit analytical software Dynaform was employed. The effects of variable blank-holder and chamber pressure on forming quality were analyzed, the matching loading curve of variable blank-holder forces and hydraulic was obtained. And the HDD system was reasonable transformed. The results indicated that at the optimized matching loading condition of the variable blank-holder forces and the chamber pressure, the wrinkling of the free area could be controlled,the thickness thinning was restrained effectually and the quality of the parts could be improved. |
