Research on Identification for Drawbead Geometric Parameters Based on Genetic Algorithm and Equivalent Model

The identification problem for circular drawbead geometric parameters was discussed. The application method of genetic algorithm and equivalent drawbead model on identification for circular drawbead geometric parameters from given drawbead restraining force was developed and programmed, in which equivalent drawbead model was used as forward solver and genetic algorithm was adopted to solve the inverse problem. The calculated results were compared with the experimental ones reported by Nine. The accuracy of this method was verified.
