“…However, few researchers investigate reliability modeling and reliability-based optimization of die-casting. Choi et al [14] investigate quality engineering optimization of robot casting considering design robustness. In their research, the tolerance of material and variation of material property are considered in quality based design optimization, and two quality engineering methods are done about same robot casting and compare with each other.…”

Die-casting is a typical multidisciplinary system, in which there are many disciplines involved such as hydrodynamics, heat transfer and elastic-plastic mechanics and their coupled relations are intricate. Moreover, there are inherently epistemic uncertainties in die-casting. This paper aims at reliability modeling and optimization of diecasting. Firstly, finite element analysis is applied to simulate the process of die-casting, and the quadratic response surface is used to represent the multidisciplinary optimization model of die-casting, in which the evidence theory is used to represent the epistemic uncertainty. Then, a reliability-based multidisciplinary optimization (RBMDO) procedure for diecasting is proposed. The results show the RBMDO procedure possesses high computational efficiency in optimizing multidisciplinary system with epistemic uncertainty.
