Abstract
In this paper, DYNAFORM software was used to simulate and analyze the stamping and forming process of automobile front floor parts. In addition, through ETA post-processing software, the animation simulation of the front floor forming process, the forming limit diagram (FLD), the change of thinning rate and the flow of materials are obtained, according to the law of change, some parameters are adjusted to obtain the optimal results. Three groups of subjects were set up: blank holder force, blank shape and draw bead, by controlling the material and the friction coefficient and other parameters are the same, respectively to compare the result of the experiment data, to get the best forming solution. Through DYNAFORM simulation and analysis, the overall forming effect of automobile front floor parts is the best under the scheme of 240 tons of blank holder force, rectangular blank shape and sectionalized sectional draw bead.
