摘要:

船舶比例方向阀控液压操舵系统中,比例阀换向时将产生压力冲击,对液压系统及船舶本身均带来不利影响.针对某船的液压操舵系统,在AMESim中建立了比例方向阀及操舵系统模型,进行了压力冲击仿真,并与实验压力曲线进行了对比,确定了模型的正确性.在此基础上进行了降低比例方向阀换向冲击研究,采用放大器输出电流优化方法,确定了输出电流为抛物线形时阀换向压力冲击较低.实验研究结果表明:采用AMESim建立的比例方向阀控操舵系统压力冲击仿真模型与实际系统基本符合,优化电流法降低压力冲击效果明显.

Abstract:

In proportional direction valve controlled ship steering system, the proportional direction valve could generate water hammer when it changes direction. Bad affects could be lead to not only the hydraulic steering system but also the ship itself. The model of proportional direction valve controlled ship steering system was created in AMESim. The model and the water hammer simulation result were correct after compared with the test result. Then the current optimization method was used to reduce the water hammer of proportional valve, the optimization result was the parabolic curve. The simulation and the examination results show that the AMESim is fit for the water hammer modeling and simulation of the steering system. The current optimization method can reduce the water hammer significantly.
