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.
In order to realize the visualization of hydraulic system with system schematic diagram, a hydraulic system modeling language based on cavity node method and a set of new modeling language description rules are presented. The realization of the program by using this modeling language The modeling language abstracts the hydraulic system topology into a graph structure with cavity nodes and element nodes.The hydraulic component model is packaged separately and can be used modularly.On the basis of modeling language description rules, Node and element node.All nodes and connection matrix make up the overall system model.The correctness and validity of this modeling description language are verified by a typical intelligent hydraulic pump system modeling process.The results show that this matrix Cavity node hydraulic system modeling language can be easily established in line with the principle of the hydraulic system topology and system schematic automatically generated system model.
