摘　　要：在深入研究Weis-Fogh机构升力特性的基础上,设计了一种基于Weis-Fogh机构的新型船舶电力推进装置。该推进装置由两片平板翼组成,工作时两翼绕共同的转轴从闭合状态向分离的方向迅速旋转而产生推力。从理论上推导出推力和旋转角频率之间的函数关系,并且在系统平均推进效率最优的原则下,得到了Weis-Fogh机构最优的工作角频率。仿真结果证明了该装置理论上的可行性。The paper presents a novel electric propulsion device for ships based on a thorough study the lift characteristics of Weis-Fogh mechanism. The device is composed of two flat wings, which rotate quickly from closed state to detached state at work. The function relationship of thrust and turning angle frequency is formulated. The best angle frequency Weis-Fogh mechanism in work is obtained to achieve the best average thrust efficiency. The simttlafion results prove, the feasibility of the device in theory.
