Research on Swarm Intelligence Optimization Method and Application of Process Parameters for Coordinated Control of Shape and Properties of Forging of Superalloy Rings
The accurate and rapid selection of the optimal combination of process parameters of forging is crucial for achieving coordinated control of the shape and properties of superalloy ring/disk forgings,which are not easily deformed.In this paper,the limitations of traditional forging process parameter design,which relies heavily on the experience of designers,challenges in selecting objective functions,and time-consuming optimization process were studied.A method for optimizing the combination of process parameters based on swarm intelligence optimization was proposed to enhance the quality of the shape and properties of superalloy ring forgings.The study focuses on the optimal combination of process parameters for the die forging of superalloy rings,aiming to achieve coordinated control of the shape and properties of the ring forgings.A multi-objective parameter model was designed,considering the average equivalent strain,standard deviation of equivalent strain,and material utilization rate of the ring forgings.Each objective parameter was weighted,a comprehensive objective model for the ring forgings was obtained.Using the central composite experimental method and finite element simulation results,the regression relationships between each objective parameter and the process parameters were determined.The sparrow search algorithm was employed to perform intelligent optimization on the comprehensive objective model,resulting in the optimal combination of process parameters for the ring forgings.Trial production results demonstrated that the technological parameter combination obtained through the swarm intelligence optimization using the sparrow search algorithm,with the grain size of the forged rings reaching grades 9～10 and the grain size difference value is less than one grade.This significantly improved the uniformity of deformation and achieved coordinated control of the shape and properties of superalloy ring forgings.
