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.
