| Research Abstract |
Objective modeling and Multidisciplinary Optimization Technique are studied for Concurrent Engineering Systems through the development of the computer aided design system for several actual design problems. The results obtained are summarized as follows :
1.A framework of computational design method and objective modeling is proposed for layout and geometry design of complicated mechanical systems. In the method, a design object is represented with a set of decorative relationships among various elements of a system i.e., apparatus, piping etc., which is gradually extended form system structure to exact layout and geometry through the design process. The configuration to be designed is made to grow and refined through the design process with evaluating their functions, cost and manufacturability etc. The system developed is applied to the design of an air-conditioning unit, and its validity and effectiveness is ascertained.
2.Multidisciplinary optimization technique is also applied for the design problems of several kind of complicated mechanical systems with referenced to the development on concurrent engineering system. The design problems developed here are link mechanisms, gear drive devices, vehicle power trains etc. In the design process of these products, various aspects must be dealt with concurrently and simultaneously, since they include a large umber of functional disciplines.
For example, in the design of link mechanisms, the multidisciplinary modeling and optimization must be applied for its linkage shape synthesis and structural strength design. To formulize and solve the problem, an object-oriented modeling and a generalized reduced optimization technique are applied. And their effectiveness is ascertained.
The design technique developed here is also applicable for other various kind of design problems including the above mentioned design.
