摘　　要：在建立舰船液压操舵系统原件动态数学模型的基础上,利用MW orks软件实现液压能源系统动态特性分析通用模型库的构建。模型库包括长管路动态模型、液压泵数学模型、液压缸数学模型和其他元件如滑阀的数学模型,并根据模型库的元件建立了舰船液压操舵系统方案设计阶段的数理模型,对舰船的液压操舵系统进行了仿真。仿真结果表明,该模型符合实际系统的管路压力和流量脉动特性,在模型中能获得时域范围内系统的流量压力脉动情况。Based on the founded dynamic mathematical models for components of ship hydraulic rudder system,the general model library for dynamic performance analysis of hydraulic rudder system was constructed using MWorks.The model library includes long lines,pumps,cylinders and other elements such as spool valve.The Modeling was made for ship hydraulic rudder system of a general ship in the setp of schematic design and simulation was also made for the ship hydraulic rudder system.The simulation results show that the model can reflect the pulse characteristics of the actual hydraulic rudder system and the time domain pulse situation of system position can be obtained in the model of the ship hydraulic rudder system.
