【Abstract】 After analyzing the experimental data of the solidified grain size in Al alloy under strong pulsed electromagnetic field, a BP algorithmic model of artificial neural network was established. The results show that the simulating results are better in agreement with the experimental results. Therefore, this BP algorithmic model of artificial neural network can be used to control the parameters and predict solidified grain size under applied strong pulsed electromagnetic field. It provides an easy and practical method and means for optimizing experimental design.[更多还原
