Development of Design Assistance System and Its Application for Engine Concept Modeling 2011-37-0030
This article presents results of the Design Assistance System (DASY) development and examples of its application for engine concept modeling. The software (DASY) for creating and maintaining knowledge database was developed. This software is targeted to simplify and speed up the concept design process. The targets were met by providing the high level of flexibility along with a simple user interface. Two examples that show interaction of DASY with computer-aided design (CAD) software are presented. The DASY creates a template for conserving the knowledge acquired during engine design in the past. It provides hints for the future design tasks by offering a data of similar engines, based on experiments and simulations at different levels of complexity and profoundness. It assists simultaneously in searching procedures suitable for engine optimization fulfilling different design, operation constraints and using different amount of input data, available according to the current stage of the design. Using output-input approach, the design and development schedule with iteration loops and parallel processes can be planned.
