Sixth Drawing Process Analysis for Electrodeposited Nickel Coating Battery Shells
A finite element method is used to simulate the sixth drawing process of nickel coating battery shells. The material’s mechanical parameters are tested and shown and the forming tool parameters are given. The Belytschko-Wong-Chiang shell elements are used and the kinematical work hardening model is adopted for the sheets. The stress-strain field in the components in the forming processes is obtained. The nickel coating yielded at the drawing process, the effective plastic strain reached 0.3769-0.7524. The coated sheet does not delaminate in the bonding interface during the deformation process. This study can aid the production of coating battery shells.
