Abstract：

In order to reduce the forming load of gear and improve the qualification rate of forgings, a union optimization method of preformed shape and process parameters based on electric field method and complex bee colony algorithm was proposed. Based on the electric field method, the candidate preformed shapes corresponding to each closed equipotential line were obtained. At the same time, selecting press speed, friction factor, billet temperature as the common optimization parameters, a multi-objective optimization model was established to reduce the forming load and improve the filling rate. Furthermore, the parameter optimization method of the complex bee colony algorithm was proposed by introducing the Metropolis selection criterion into the artificial bee colony algorithm and using the complex optimization method. It was verified that the parameters optimization result of the complex bee colony algorithm was better than that of the traditional artificial bee colony algorithm. Through simulation and actual production verification, the maximum forming load of the forging process is reduced from 1960 kN to 1550 kN, and the product qualification rate is increased from 91.7% to 100%, which verifies the effectiveness of the union optimization method of preformed shape and process parameters.
