高功率密度斜向支柱锥齿轮辐板结构设计优化
Optimal Design of a Tilting Prop Bevel Gear Spoke Plate Structure with High Power Density
摘要
Abstract
To meet the urgent need for the lightweight design of gears under complex conditions in helicopter transmission systems,a design optimization method is proposed for a tilting prop bevel gear spoke plate structure with a high power density.Based on the variable density method considering stress constraints,topology optimization and reconstruction of the bevel gear spoke plate structure are performed,which yield a novel tilting prop bevel gear spoke plate structure with a high power density,differing from the traditional configuration.Introducing an evolution factor and the Markov chain based on the traditional particle swarm optimization(PSO)algorithm,an intelligent and advanced switching delayed PSO(SDPSO)algorithm is developed.The SDPSO algorithm can adaptively select switching strategies and delay information,and it is employed for the size optimization of a tilting prop bevel gear spoke plate structure.After optimization,the mass of the bevel gear spoke plate is reduced by 19.24%,and the maximum von Mises stress of all the operating conditions is reduced by 7.27%.Additionally,the stress distribution of each operating condition becomes more uniform,which demonstrates the structural advantages of the designed bevel gear spoke plate and the superiority of the proposed optimization method.关键词
