Simulation Results

Based on the analysis of now available evaluation indexes to estimate the formability of T-shaped tube hydroforming, an aggregative indicator is proposed. The effect of load path on the formability of T-shaped tube is discussed by FEM simulation, and validity of the evaluation index and simulations are proved by experiment. Results show that with the broken line load path of 0-35-35-60, the value of aggregative indicator is the greatest and the formability is the best. The optional parameters are testified by experiment and the results are in agreement with the FEM simulation results.

Using Data

We performed numerical simulations and multiobjective optimization of a hydroforming process for copper tees using the BCJ plasticity material model developed by Bammann et al., which accounts for material manufacturing and history effects. A finite element simulation of the hydroforming process was created using data from experiments and the industrial process. The process parameters and geometry factors were optimized using a multiobjective optimization methodology employing metamodeling and software developed at Mississippi State University’s Center for Advanced Vehicular Systems.

Simulation Results

Based on the analysis of now available evaluation indexes to estimate the formability of Variable cross-section Y-shaped tube hydroforming, an aggregative indicator is proposed. The effect of load path on the formability of Variable cross-section Y-shaped tube is discussed by FEM simulation, and validity of the evaluation index and simulations are proved by experiment. Results show that with the broken line load path of 0-30-30-40, the value of aggregative indicator is the greatest and the formability is the best. The optional parameters are testified by experiment and the results are in agreement with the FEM simulation results.
