Numerical Simulation And Technical Analysis Of Compound Spinning Of Abnormity Works

Curvilinear generatrix spinning of cylinders is a techniques that is based on tube spinning. In this paper, aiming at U-shape gland, with the analysis of deforming features and rule of deforming for curvilinear generatrix spinning of cylinders, finite element theory is applied to process of deformation, which provide experimental analysis and manufacture of realistic product for complex spinning of cylinders with necessary reference. Taking boundary condition, contact, friction and spatial trajectory into account complex spinning of cylinders according to the dimension and deformation with realistic work-piece. ANSYS software is applied to 3D numerical simulation of U-shape gland. The stress and strain distributions on shaping are obtained, and the plastic flow law and deformation mechanism of the metal with respect to U-shape gland deformation were analyzed. Figuration of U-shape gland, rule of variety of stress, strain and spinning force with ratio of thinning and feeding, the thick of the work-piece and the diameter of the roller were analyzed. In the end, associate with experiment, all kinds of vices of U-shape gland deforming were analysis as well as how to be. From the result we can see that it is feasible to shape up the U gland with the process method of spinning. The method of numerical simulation can provide important consult to factual production.
