    摘要:

    针对转叶舵机操舵过程中所受水动力负载复杂且与转舵角度、角速度构成强力位耦合关系,严重影响舵机系统控制性能的问题。在分析舵叶表面流体力的基础上,提出一种新型复式液压摆动缸结构解耦的方案。该复式液压摆动缸为双层结构,内层为驱动缸转子,采用中空结构,通过孔轴配合与舵杆装配成一体;外层为力矩解耦缸转子,兼做驱动缸壳体。驱动缸转子嵌套在解耦缸转子内部,控制舵机的转向、转速和转角;解耦缸转子与驱动缸转子同向转动,施加主动力矩作用在驱动缸转子上,抵消舵叶转动引起的水动力负载对驱动缸转子运动姿态的干扰,消除水动力对舵角控制的影响。通过仿真分析和实验表明,复式液压摆动缸结构解耦的有效性。

    Abstract:

    Aiming at the problem that the hydrodynamic load received by the rotary vane steering gear in the process of steering is complicated and it forms a strong position coupling relationship with the steering angle and angular velocity, which seriously affects the control performance of the steering gear system. Based on the analysis of the fluid force on the surface of the rudder blade, a new structure decoupling scheme of the compound hydraulic swing cylinder is proposed. The compound hydraulic swing cylinder is a double-layer structure, the inner layer is the rotor of the driving cylinder, and the hollow structure is adopted, which is assembled with the rudder stock through the hole shaft. The outer layer is the rotor of the torque decoupling cylinder, which is also used as the shell of the driving cylinder. The rotor of the driving cylinder is nested in the rotor of the decoupling cylinder to control the speed and angle of steering gear. The rotor of the decoupling cylinder and the rotor of the driving cylinder rotate in the same direction, and the active torque is applied on the rotor of the driving cylinder to counteract the interference of the hydrodynamic load caused by the rotation of the rudder blade on the motion posture of the rotor of the driving cylinder, so as to eliminate the influence of the hydrodynamic force on the control of the rudder angle. The simulation analysis and experiment show that the structure decoupling of compound hydraulic swing cylinder is effective.
