Forming analysis for automobile covering panel based on dynaform

The difficulty of automobile covering panel forming is that the model surface is complex and the process is hard to determine. But it is capable to get high quality of forming panel with the help of computer using numerical simulation to adjust process. The application of numerical simulation in die designing and some key problem in Dynaform are researched in the paper, and an example of a complex covering panel is presented, The forming of it is simulated and analyzed by using Dynaform And then the die of the covering of panel is designed, The paper supplies an instruction of digital designing and manufacturing of dies.
