Applied research on extension element model in hydraulic system

This paper further researches the application of extension element model of hydraulic system. A extension element model of hydraulic system contains three parts: the prototype of a hydraulic component, the matter-element and relationelement model of hydraulic components, and the matter-element and relation-element model of hydraulic systems. The foundation building a extension element model of hydraulic system is to build its database of the prototypes of a hydraulic component. The matter-element and relation-element model of hydraulic components is a model for physical hydraulic components. The the matter-element and relation-element models of hydraulic components on a hydraulic system can describe the internal links among hydraulic components. Through analysis of the connections among the matter-element and relation-element models of hydraulic components, rings, power bond graphs, and dynamic equations will be found and gained. Thus, the performance and digital simulation for a hydraulic system will be realized and finished.
