建立液压系统信息模型的研究

所设计的液压系统信息模型将液压系统分作系统、元件和油口3个层次，以多层链表的方式将其连接起来，能简单地与液压系统一一对应。而使用液压系统信息模型的整个仿真系统也分为3层，以信息模型为核心，向上层映射为数学模型，向下层映射到数据库。研究结果表明：所采用的体系结构弹性足，构造灵活，不但能满足液压仿真的需要，而且对系统的扩展性、对多方应用间信息集成都有着良好的支持。

On Information Model of Hydraulic Systems

An information model of hydraulic system is introduced, which uses 3 types of objects: system object, component object and gun object. These objects are organized by a multilayer list, and the list is easily mapped to hydraulic system in one-to-one correspondence. The hydraulic simulation system, based on the information model, is designed as 3 layers too. On the system, the information model is easy to be mapped as mathematics models that are at upper layer, and mapped as records of database that are at bottom layer. The method is flexible apparently, and can be used to build a simple system of hydraulic system simulation.
