摘要: 围绕海洋强国战略,发展高性能的海洋技术装备,对于提升资源开发能力以及海上国防力量具有重要意义。提出一种基于四五杆平面位置解耦机构的摆线推进器构型,对其进行运动学和力能学建模,并以此为依据研制互补对称摆线推进器样机。通过设计样机的平面复合运动工况,开展互补对称摆线推进器的公转转速、叶片展长等物理参数对样机平面复合运动性能影响的试验研究。结果表明,通过调节两个摆线推进器的前进角和转向角,可分别实现样机在平面360°范围内沿任意方向移动,以及前进中转向,甚至原地转向的功能。公转转速越高,样机的平面移动速度和推进力越大,推进效率和转弯半径对公转转速的变化并不敏感。叶片展长越长,平面移动速度和推进力越大,推进效率呈现先增大后减小的趋势,转弯半径无明显变化。研究结果对设计和使用摆线推进器均具有很大的指导意义和应用价值。

Abstract: The development of high-performance marine technical equipment around the strategy of marine power is of great significance for enhancing the capability of resource development and maritime national defense. A configuration of a cycloid thruster based on the decoupling mechanism of four or five rod plane positions is proposed, and its kinematics and energetics are modeled. Based on this, a complementary symmetrical cycloid thruster prototype is developed. By designing the plane compound motion condition of the prototype, an experimental study is carried out on the influence of the orbital speed, blade length and other physical parameters of the complementary symmetrical cycloid thruster on the plane compound motion performance of the prototype. The results show that by adjusting the advancing angle and steering angle of the two cycloid thrusters, the prototype can move in any direction within the range of 360° on the plane, and turn while advancing, and even turn in situ. The higher the revolution speed, the greater the plane moving speed and propulsion force of the prototype, and the propulsion efficiency and turning radius are not sensitive to the change of revolution speed. The longer the blade length is, the greater the plane moving speed and the propulsion force. The propulsion efficiency first increases and then decreases, and the turning radius does not change significantly. The results have great guiding significance and application value for the design and use of cycloid thrusters.

Key words: cycloid propeller, complementary symmetrical configuration, planar compound motion, four-five-bar mechanism
