| dc.description.abstract | Gear manufacturing processes typically begin with shaping the teeth from a steel blank, followed by induction hardening to enhance tooth strength. Subsequently, precision machining is performed to achieve gear accuracy. In response to energy conservation and carbon reduction, the final precision machining step is omitted, simplifying the gear
manufacturing process. To achieve this goal, predicting the characteristics of gears after induction hardening becomes a crucial tool. This study proposes the application of uniform experimental design for experimental planning of cylindrical gear induction hardening. A predictive model is established using radial basis functions to anticipate gear characteristics after induction hardening, with the derivation of respective target prediction equations. Additionally, finite element analysis is employed to simulate gear induction hardening, advocating the use of a non-uniform magnetic field model for enhanced accuracy. Subsequently, particle swarm optimization is utilized to determine optimal heating control factors for specific gear features. Finally, applying the optimal solution to finite
element simulation produces results for the non-uniform magnetic field model, validated against predictive model outcomes. A comparison between non-uniform and uniform magnetic field models and predictive model results validates the necessity of employing a non-uniform magnetic field model. In conclusion, this study proposes that the predictive model is more suitable for forecasting characteristics in the induction. | en_US |
