摘要
针对航空发动机管路布局目前存在的问题,提出一种基于改进多目标萤火虫算法(improved multi-objective firefly algorithm,IMOFA)的航空发动机管路多目标优化布局方法.在该方法中,首先以管路长度最短、弯头数最少以及能量值最小为优化目标,建立了航空发动机管路多目标优化布局数学模型.然后,结合自适应扰动策略和精英策略,提出了一种应用于航空发动机管路多目标优化布局的改进多目标萤火虫算法,从而实现了航空发动机管路的多目标优化布局.最后,通过实例验证了所提出方法的可行性和有效性.
To solve the existing problems of pipe routing layout for aero-engines,a multi-objective optimization layout method of aero-engine pipe routing based on improved multi-objective firefly algorithm(IMOFA)is proposed.In the method,the multi-objective optimization layout mathematical model of aero-engine pipe routing is established,which takes the shortest pipe length,the least number of elbows,and the minimal energy value as the optimization objectives.Then,by combining with adaptive disturbance strategy and elite strategy,an IMOFA algorithm for multi-objective optimization layout of aero-engine pipe routing is provided,which realizes the multi-objective optimal layout of aero-engines pipe routing.Finally,the feasibility and effectiveness of the proposed method is verified by case studies.
