摘要：

Large thinning ratio is a difficulty in spinning process of ellipsoid components, which needs to be solved to ensure the accuracy of parts. Based on the method of reverse deformation, two different variable thickness blanks were designed: (1) variable thickness blank based on thickness reduction of the conventional spinning process; (2) variable thickness blank based on sine rate of the shear spinning process. Then, the two methods were applied in the spinning simulation of ellipsoid thin-walled curvilinear parts with large diameter-thickness ratio. The results of simulation showed that variable thickness blank could significantly improve the forming quality of the forming parts.
