摘要: 为实现直观面向系统原理图对液压系统建模,提出了一种基于容腔节点法的液压系统建模语言和一套新的建模语言描述规则,并阐述了利用该建模语言进行程序实现的方法.该建模语言将液压系统的拓扑结构抽象成具有容腔节点和元件节点的图形结构.液压元件模型独立封装,可模块化使用.在建模语言描述规则的基础上,生成容腔节点与元件节点的连接矩阵.所有节点和连接矩阵构成了系统的整体模型.通过典型智能液压泵系统建模过程,验证了该建模描述语言的正确性和有效性.结果表明:该基于容腔节点的液压系统建模语言可方便建立符合液压系统原理的拓扑图,并面向系统原理图自动生成系统模型.

Abstract: To achieve schematic-oriented modeling directly on the hydraulic system, a new modeling language based on finite volume and a new set of rules to describe the modeling language were proposed, also the corresponding procedural method was described. Based on the modeling language, the topology of the hydraulic system was abstracted to graphical structure with volume nodes and elements nodes. The components model was defined and packaged independent. Coperating with describing rules, the connection matrix of volume nodes and components would be generated. The overall system model was constituted by all nodes and the connection matrix. By typical intelligent hydraulic pump modeling process, the validity and effectiveness of this modeling language was proved. The results showed that by this language, the topology was established easily, and schematic-oriented hydraulic system model was generated conveniently.
