风翼回转液压系统控制策略仿真及实验研究

Simulationand Experimental Research of Control Strategy in Wing-sail Slewing Hydraulic System

风翼回转液压系统是风翼助航船舶必不可少的一部分。在实际运行过程中,要求此液压系统能够稳定运行,压力波动小。对风翼回转液压系统在AMESim中建立仿真模型,在给定4种不同起动和制动控制信号的情况下,分别在仿真模型和实验台液压系统中比较压力波动和峰值压力,找出最适宜的起动和制动信号。在确定控制信号的基础上,通过对比不同起制动时间下系统的动态特性,最后确定系统最佳起动和制动时间。为风翼的实船应用奠定了基础。

The wing-sail slewing hydraulic system is an essential part on wing-sail assisted ships. In the process of actual operation, this hydraulic system is required to operate steadily and to have a small pressure fluctuation. According to the wing-sail slewing hydraulic system, the simulation model was established in AMESim. Under the circumstances of given four different control signals of starting and braking, the pressure fluctuation and peak pressure were compared in the simulation model hydraulic system and experi- ment table system, so as to find out the most appropriate starting and braking signal. Based on determining the control signal, by comparing the dynamic performance of system in different control time of starting and braking, the optimum starting and braking time of system is determined finally, which has laid a foundation for the further application of wing-sail ships.
