摘要
提出了一种新型的流体推进器——单叶片推进器,通过对叶片的运动学和负载的分析,建立了该推进器的运动方程。基于ADAMS环境,建立了单叶片推进器的虚拟样机,并进行了推进器系统的动力学仿真。仿真分析表明:单叶片推进器能够在设定转速下稳定运行;有效推力是脉动变化的,但在稳定转速下,有效推力的幅值和频率是稳定的,可以产生稳定的推动效果。
A new type of liquid propeller--single-blade propeller is discovered and its dynamic equations are established by means of kinematic analysis of the blade and loads applied on the blade. The prototype of the single-blade propeller based on the ADAMS using the derived equations is constructed so that the dynamic analysis and simulation of the system can be done automatically. The results from dynamic simulation of the new propeller demonstrate that it can run smoothly at desired speed, and the effective propelling force from the blade changes in the form of pulse wave in magnitude, but its peak and frequency keep constant under even rotation.
