RESEARCH ON FORMING TECHNOLOGY OF AUTOMOBILE FRONT FENDER
In this paper, according to the orthogonal experiment principle and making use of Pamstamp2G software，the numerical simulation was made on different blank-holding force，the rubbing factor between die and sheet bar. Through an analysis and comparison between the thickness of sheet bar got from numerical simulation and from practical forming part，the effects of the factors mentioned above on the forming results of front fender was arrived at，and the optimized technological condition for the forming was pre-estimated.
