|
An algorithm for the sheet hydro-forming was developed,which was based on BT shell element and dynamic explicit method,the areas on which liquid pressures act were judged,and the liquid forces was computed. The algorithm was integrated into self-developed software FASTAMP which was used to the numerical simulation of drawing process,and was applied in the automobile panel hydro-forming. The simulation of a practical automobile body metal sheet,namely a truck top cover part,was done with a practical load path. According to fold and burst defect in hydro-forming,the practical load path was optimized,the performance of the part was improved. The precision and the practicability of the algorithm for hydro-forming were validated by the agreement between the simulation results and the experimental results.
