Design and optimization of elimination tool in rubber forming of TB5 titanium

  • Wrinkling will occur in the rubber forming of convex flange, even for the forming of TB5 titanium when the flange height is higher. Wrinkling was quantified as objective functions. The rubber forming process with different side blank holder parameters were simulated based on the optimum design and FEM. Influences of different side blank holder parameters on the wrinkling were analyzed. The relationship with forming index was approximately expressed as a polynomial function. Optimal parameters were obtained using proper optimization methods based on the response surface methodology and quasi-Newton method. Practicability and validity of the optimization methods proposed in this work were verified by experiments.
