| 摘 要： | 以双转子混合排气涡扇发动机为研究对象,研究了粒子群算法(PSO)应用于航空发动机性能仿真时,控制参数对模型收敛性的影响,并结合N+1点残量法的优点,提出了在模型不收敛点采用粒子群算法与N+1点残量法交替计算的混合算法。理论分析与数值仿真结果表明,该算法既保持了N+1点残量法的高效率、高精度计算,又继承了粒子群算法大范围收敛的优点,可实现模型大范围、高效率、高精度收敛。

| Abstract: | Taking the two-spool turbofan engine as the research object,the effects of control parameters on convergence model was investigated as Particle Swarm Optimization(PSO) was used for aero-engine performance simulations.Then combined PSO with N+1,an improved hybrid algorithm was offered,which was used for unconverged points of model.In the improved hybrid algorithm,N+1 was also the main solution and PSO alternated with N+1 when N+1 diverged.Theoretical analysis and performance simulation results showed that th... |
