Abstract
In this paper, a simulation analysis is conducted for liquid-filled deep drawing process of battery shell used on electric vehicles. Firstly, the plate liquid-filled forming experiments are conducted on our own hydraulic forming experimental platform, secondly, the hydraulic simulations based on the nonlinear finite element software DYNAFORM are conducted to demonstrate correctness of the finite model and the simulation method, and finally, based on the correctness of the finite element simulation method, finite element modeling and simulation analysis for the battery shell of electric vehicles are conducted to discuss the impact of different presser ring edge pressures and hydraulic pressures on the wall thickness of the battery shell, providing a reference for the practical application of the liquid-filled deep drawing process of battery shell.
