OBJECT-ORIENTED CAD FOR PRACTICAL HYDRAULIC SYSTEM-DESIGN

This paper describes a new approach to the design and implementation o f object-oriented CAD for hydraulic systems. This CAD tool is an intel ligent computer assistant for hydraulic engineers, to aid them in desi gning their own systems. Work has been devoted to a new class-modellin g method for the object model of this CAD system. The method can model the behaviour of existing hydraulic circuits and components more rigo rously, to avoid errors. Physical data about hydraulic systems has als o been captured in the data model for another application, namely flui d power-system assembly problems, and this will be briefly described. An application example, a deep-drawing press, has been selected to ill ustrate the usefulness of the CAD system. Copyright (C) 1996 Elsevier Science Ltd
