| Abstract: | The process parameters of electric upsetting acted as studying samples. Velocities of upsetting cylinder and anvil cylinder, pressure of upsetting cylinder used as input parameters, heating current was as target parameter. Studying samples were modeled and optimized with Levenberg-Marguardt algorithm of BP neutral network models. The prediction results of the neutral network were compared with the determined results indicated that the BP network can be satisfactorily used to realize prediction of heating current in the electric upsetting. |
