Robust Optimization for an Autobody Outer Panel Stamping Process

Abstract

Abstract: In the case of an autobody outer panel stamping process, a metamodel based on FEsimulation, design of experiment, response surface methodology(RSM) and MonteCarlo method was constructed and the deterministic optimization result was obtained. By constructing and solving the robust optimization model composed of mean and standard deviation of quality index, the robust optimal solution was obtained and compared with the deterministic optimization result. It is demonstrated that the product quality variations are reduced significantly, and quality targets (reject rate) are achieved under the robust optimal solution. This method can also be used during the early phase of product and tooling design to reduce commissioning period.

Key words: sheet metal stamping, robust design, outer panel, stochastic analysis, robust optimization
