Design and Intelligent Optimization of Casting Process of Shell Castings Based on Cast Designer
The casting simulation analysis software Cast Designer was used to complete the auxiliary design of the pouring system through the castability evaluation system DFM.Then,the DOE technology and the intelligent optimization technology based on genetic algorithm GA were used to evaluate the impact of different process design schemes and casting process parameters on the quality of the shell castings,and analyze the relationship between the yield and the shrinkage under different riser,chill and pouring temperatures.According to the analysis of DOE simulation results,it is found that the size of top riser and side riser is the key factor affecting the material yield and shrinkage volume.Then the genetic algorithm GA was used to select the optimal design scheme and parameters,and the optimal process scheme for shell casting is obtained through Pareto curves.
