Simulation of Drawing Process for Spring Seat of Spiral Step and Multiobjective Optimization

Abstract:

Finite element model of drawing is established and numerical simulation analysis is made based on the manufacturing status of uneven thickness distribution and frequent fracture occurrence of drawing spring seat of spiral step , and regression model of the maximum thinning rate and the maximum thickening rate of the drawn workpiece is established by taking the punch radius and clearance between punch and matrix of the workpiece as influencing factors. In addition, comprehensive quality evaluation model is created via multiobjective optimization and optimal punch radius and clearance is computed. The optimization scheme is proved to be feasible and effective through experimental verification.
