摘　　要：泵控液压缸操舵系统因工况复杂、负载变化大、变量泵装置惯量较大等因素,使其产生的压力冲击对系统效率、平稳性及准确性造成了不利影响。首先对泵控液压缸操舵系统进行物理建模,采用Simulink对系统进行动态特性的仿真研究;其后在AMESim软件中建立泵控液压缸操舵系统模型,仿真液压缸压力冲击,并与Simulink仿真结果对比,确定模型的正确性。在此基础上,重点分析航速、伺服控制系统中阀控液压缸弹簧弹性系数以及舵角速度对系统冲击特性的影响,据此得到减小压力冲击的设计方法和控制结论,为改善泵控舵的性能提供理论依据。In pump-controlled hydraulic cylinder steering system,the pressure shock generated by complex working conditions,load changes and large inertia of variable piston pump make adverse impact on efficiency,stability and accuracy of the system.In this paper,the dynamic characteristics of the pump controlled steering system were achieved by using the Simulink toolbox to carry out physically modeling and simulation.Then the simulation model was created in AMESim software to study the characteristic of pressure shock.The simulation model of AMESim was proved to be correct,which compared with the results of Simulink.Moreover,the speed of ship,the spring coefficient in feedback mechanism,and the speed of rudder were analyzed to study the impact of pressure shock of the system.Analysis of the simulation can provide a theoretical basis for reducing pressure and control conclusion of improving the performance of the pump controlled hydraulic cylinder steering system.
