Abstract: Aiming at the problem that the prestripping of the copper pole piece failed to lead to subsequent peeling,the shear stress of copper starting sheet joint and titanium seed plate joint was analyzed by using the theory of material mechanics. According to the thickness of the titanium plate and flexural force, nine kinds of combinations were designed. The threedimensional model was established for each combination, and simulated by using ANSYS Workbench software. By analyzing the interface shear stress and the plate structure deformation. Find out the influence of the set variables on the predelamination phase of the copper pole piece，determined the better combination that good for improve the quality and efficiency of copper stripping quality with less damage to the titanium starting plate. The results indicate that the shear stress reaches the maximum at the copper proplate interface, explaining the reason for the opening of the projectile. Choosing a smaller thickness of the titanium plate and placing the force in the deflecting near the interface will be more conducive to prepeel.
