波浪可以为海上航行器提供运动的能量,实现长时间、大范围的机动运动。一般认为波浪能驱动推进机构的水翼的摆角对推进性能有显著影响。本文提出了一种确定波浪驱动机构最优水翼倾角的方法。基于绝对坐标系和Kane方程建立了通用波浪驱动推进机构的动力学模型,确定了模型中波浪产生的推进力组成,采用"机构冻结"的方法,计算了任意时刻水翼的最优转角,分析该角度与推进机构瞬时速度的关系。该研究对于改进推进机构的设计、合理规划水翼摆动规律具有借鉴意义。
Abstract：Wave can provide energy for locomotion of marine vehicle to implement motion with a long time and a large range journey. It is well recognized that the rotational angle of hydrofoil of propulsion mechanism driven by wave plays an important role on locomotion performance. A method to determine optimal angles of hydrofoil of propulsion mechanism is carried out. Dynamic model of propulsion mechanism is developed with suitable assumptions. The item of propulsion force is drawn. Based on "frozen mechanism" principle, the optimal angle of hydrofoil is calculated and the relationship between rotation angle of hydrofoil with accession velocity is studied. The work is useful for the design of propulsion mechanism and planning of hydrofoil oscillation motion.
