针对当前船舶液压系统科研和教学过程中传统实物设备的封装性、隐蔽性、抽象性等不足，提出并实现了一套模拟和再现液压系统整体工作场景和液压油流动特性的可视化仿真系统。运用纹理映射方法对管道内液压油的流体特性及形态进行模拟；运用数值方程对液压系统工作机制和液压油动力学规律进行模拟，成功地仿真了船舶起货机液压系统的工作过程，为船舶起货机液压系统的科学研究和教学训练提供了有效手段。
Abstract
This paper aimed at the encapsulation, concealment and abstract problems of traditional marine hydraulic equipment during research and teaching, proposed and implemented visual simulation system to emulate the entire hydraulic system working procedure and hydraulic oil flow characteristic. Texture mapping method is used to simulate appearance of hydraulic oil in pipe; numerical equations are used to simulate hydraulic component working mechanism and hydraulic oil dynamics, marine crane hydraulic system working principle is successfully simulated. New effective approaches are provided to scientific research and training of marine crane hydraulic system.
