油船货油阀液压系统的建模与数值仿真

Modeling and simulation on hydraulic system of tanker cargo oil valve

作为油船货油装卸操作仿真系统的一个子系统，对驱动油船货油系统中各种液控货油阀的液压系统进行了数值建模仿真．首先综述了液压系统的组成及工作过程．之后，根据操作要求，分别对系统的状态参数（压力、液位等）及各元件的液压油泵的工作状态进行了仿真建模并给出了数值求解方法．

This paper sets a model to simulate the working process of hydraulic pressure system of tanker cargo oil valve. It first briefly states the working process of the real system, and then sets a function model to the system. After analysing in theory, the paper develops a set of simulating models to get the system working parameters so as to meet the requirement of dynamic training.
