Process parameters optimization of sheet metal forming in drawing process based on the technology of genetic algorithm and artificial neural network

Based on the combining of numerical simulation and artificial neural network,the mapping relations of process parameters and sheet metal forming quality in drawing process are established.It has enough precision and less times of numerical simulation.Based on the artificial neural network model,several process parameters of sheet metal forming in drawing process are optimized using genetic algorithm.The test results show that the algorithm has a good optimization effect.
