Abstract:
Stiffness belongs to the performance properties of stamping parts,and refers to ability of exterior force resistance.The influence factors of stamping part stiffness are not known clearly today.In this paper,original steel sheet is taken as a research object.By dynamic-explicit FEM software,stiffness properties for different thickness and different strength steel sheet are analyzed,and the influence of thickness,strength,elastic module,Possion's ratio on sheet steel stiffness is proposed.The research method and research result of the paper is the solid base for proposing the influence factors of real stamping parts.
