摘　　要：针对目前无轴推进器电机与水力部件设计时多未考虑两者耦合的问题,本文提出两者耦合的优化设计方法。采用多参数非线性优化方法,基于电机和导管螺旋桨设计理论公式,并考虑无轴推进器电机转子的直径等同于螺旋桨内径加上叶梢间隙,以及螺旋桨输出转矩加上间隙的摩擦转矩值作为电机输入转矩的关系,建立了一种新型优化设计模型,通过优化方法进行迭代分析,利用5.5 kW无轴推进器进行方法验证。研究结果表明,所提出的优化方法有效地考虑了无轴推进器电机与水力部件的耦合关系,可对推进器效率进行综合优化。In view of the problem that the coupling between the shaftless propeller motor and the hydraulic components is not considered at present,a coupling optimization design method is proposed in this paper.A new optimization design model is established by adopting the multi-parameter nonlinear optimization method based on motor and ducted propeller design theory formula,and by considering that the rotor diameter of the shaftless propeller motor is equal to the inner diameter of the propeller plus the tip clearance,and that the torque of the output of the propeller plus the friction torque of the clearance is used as the input torque of the motor.The iterative analysis is carried out by the optimization method which is validated by 5.5 kW shaftless propeller.The research results show that the proposed optimization method effectively considers the coupling relationship between the shaftless propeller motor and the hydraulic components,and can comprehensively optimize the propeller efficiency.
