The Application of Particle Swarm Optimization Arithmetic in Propeller Design

摘要：

　　In order to obtain a propeller with good efficiency and cavitation performance, the propeller sections were optimization designed using particle swarm optimization (PSO) method.An interactive calculation method was used in design process for the circulation distribution of designed propeller was not coincident with optimization circulation.The difference of circulation was de fined as correction factor to adjust lift coefficients of sections.PSO method was used to optimize sections to improve the lift-to-drag ratio and pressure distribu tion.The convergence condition was the circulation distribution fulfilled opti mum circulation distribution form.A MAU propeller was optimized using the method.Hydrodynamic performances of propeller and sections pressure dis tribution of original propeller were compared with optimized propeller.It indi cates from the results that compared with traditional method, the PSO method is simpler in theory and cost less computing time.The open water efficiency of optimized propeller advanced obviously.The min negative pressure is smaller which means the cavitation performance is better.
