Interactive Coupling Parameters Optimization for Stamping Quality of Rail Vehicle Reinforcing Plate
In order to reduce the maximum wave reduction rate and improve the drawing quality of reinforcement plate of rail ve-hicle,a process coupling parameter optimization method based on elite bee colony algorithm is proposed.The numerical simulation model of reinforcing plate stamping is established,and the accuracy of the model is verified based on the manufacturer's data.An optimization model with the constraint of surface wrinkling and the goal of minimizing the maximum wave reduction rate is estab-lished,and the coupling of process parameters is analyzed.By analogy,the optimization problem of process coupling parameters is transformed into the optimization problem of bee colony algorithm.The social group elite learning strategy is introduced,the con-cept of virtual elite core is defined,and the bee guided update method based on virtual elite core is used to design the process cou-pling parameter optimization step based on elite bee colony algorithm.The experimental results show that the average value of the maximum wave reduction rate of the reinforcement plate optimized by the elite bee colony algorithm is 25.24%lower than that be-fore the optimization(manufacturer's products),which effectively improves the drawing quality of the reinforcement plate.The ex-perimental results verify the superiority of elite bee colony algorithm in the optimization of drawing parameters of reinforcing plate.
