Power Transmission and Motion Control (PTMC 2005)
In this paper a method for supporting conceptual design work of hydraulic components is presented. It links together the graphical domain of sketches/drawings with the symbol domain for reflecting the physical effects and the domain of mathematical models for their quantification. The graphical domain is realised with a standard CAD program. The designer specifies his/her concepts by drawings. The functional roles of drawing entities are declared by predefined symbols associated to these entities. In this way, the designer declares his/her physical understanding and generates automatically a mathematical description. The mathematical model for each effect is stored in a database in a notation used by the symbolic manipulation program Maple. The geometrical and material design parameters of these individual effects can be linked to parameters given by some design entities. The models of each effect are combined to a set of equations describing the whole system.
Currently, the database symbols and the application are developed for hydraulic components. To exemplify the method and the capacity of the software the conceptual design of a fast hydraulic 2/2-way-switching valve with a positive feedback metering edge is modelled.
