摘要
修正多层复合材料飞轮转子因过盈装配产生的应力的计算方法,给出一种飞轮转子在纤维缠绕时产生的应力的计算方法;研究基于改进海明距离的种群初始化方法和基于进化代数的反馈变异方法,提出反馈自适应遗传算法(Feedback adaptive genetic algorithm,FAGA);利用FAGA算法,考虑应力约束、质量约束,以储质量储能密度(EPM)、成本储能密度(EPC)为目标,探讨多层复合材料飞轮优化问题。仿真分析验证了应力计算方法的合理性和FAGA算法的寻优能力,揭示了应力约束、质量约束及设计目标对内外径比、转速、EPM、EPC的影响规律。
The stress calculation method of the flywheel rotor caused by interference assembly is improved.The calculation method of stress caused by filament winding is given.The feedback adaptive genetic algorithm(FAGA)is proposed which gives the population initialization method based on the improved Hamming distances and a feedback mutation method.Based on the FAGA algorithm,considering the stress constraints,mass constraints and different design objectives of the energy per unit mass(EPM)and the energy per unit cost(EPC),the optimization design is carried out.The simulation analysis verifies the rationality of the stress calculation method and the optimization ability of FAGA algorithm.At the same time,it also reveals the influence of the stress constraints,mass constraints and design objectives on the inside and outside diameter ratio,speed,EPM and EPC.
