摘要
为了进一步指导大功率全回转推进器回转系统的设计制造,从负载计算、系统设计、仿真控制到样机测试各个方面对大功率回转推进器的回转液压驱动系统进行研究.使用水动力仿真研究方法,得到全回转推进器不同进速系数下不同回转角度下的回转负载力矩,通过与敞水实验结果的对比证明了仿真的正确性和合理性,并总结出回转负载力矩波动频率与浆叶转速的关系;根据回转负载设计单泵三马达闭式液压转舵系统,同时考虑机械系统齿轮啮合与液压系统压力波动,使用AMESIM和Adams搭建联合仿真模型,通过速度PID反馈控制实现推进器180°回转.频谱分析结果表明,负载的波动严重影响了传动系统内部的齿轮啮合力及液压系统压力.通过实船试验验证了系统设计和仿真控制的合理性.
The hydraulic steering drive system of the high-power azimuth thruster was studied from load calculation,system design,simulation control to prototype test,in order to further guide the design and manufacture of the highpower azimuth thruster steering system.The hydrodynamic simulation method was used to obtain the steering load moment of the azimuth thruster under different advance coefficients and different steering angles.The validity and rationality of the hydrodynamic simulation were proved by comparing with the results of the open water experiment.The relationship between the fluctuation frequency of steering load moment and propeller blade rotation speed was summarized.A single-pump three-motor closed hydraulic steering system was designed according to the steering load.Considering the gear meshing of the mechanical system and the pressure fluctuation of the hydraulic system,a cosimulation model was built using AMESIM and ADAMS.The 180°rotation of the thruster was realized by speed PID feedback control.Through spectrum analysis,it was found that the load fluctuation seriously affected the gear meshing force and the hydraulic pressure inside the transmission system.Finally,the rationality of the system design and simulation control was verified by the real ship test.
