摘要：
It is necessary to optimize the die structure for the low-pressure casting of aluminum alloy wheel hub which is prone to shrinkage cavity and porosity. This paper simulated the mold filling and solidification process when the change of the temperature field and stress field, based on the solidification mold defect factors in central composite experiment and response surface analysis to optimize method, finally complete the multi-objective optimization using the algorithm of the NSGA-II reasonably come to the abrasive wall thickness values. In terms of experimental verification, the phase structure of aluminum alloy casting was observed to be uniform and smooth without shrinkage cavity and porosity, which realized the lightweight design of the die and improved the quality of the die casting.
