英文摘要：

On the base of orthogonal optimization of injection molding process parameters for plastic square,the functional relationships between process parameters and flow residual stress was established.By use of regression analysis,an explicit functional relationship was established between process parameters and flow residual stress.Then,an implicit functional relationship between process parameters and flow residual stress was established using artificial neural network.Lastly,process parameters were optimized with the explicit functional relation adopting simulated annealing algorithm.The optimal result was compared with the result of orthogonal optimization to validate the rationality.It was of important to study the effect of process parameters on flow residual stress and forecast the flow residual stress of injection product.
