Research On Rapid Design System Of Centrifuge

Confronted with the more and more drastic market - competition, how to shorten the developing period and how to enhance the success ratio of the product design have become a pressing obligation for each enterprise. This paper discussed the technology of the rapid design for mechanical products, and successfully developed "the rapid design system for the centrifuge" based on the theory of CBR (Case-Based Reasoning).Centrifuges are the environmental protection equipment, which are used to deal with all kinds of life and industrial waste water. Development of this kind of product is encouraged by government. The key techniques during centrifuge development are the high rotate-speed, the complicated control system and the strict demands on manufacture and assemble. Traditionally, the designing period of a centrifuge, from calculating on technical parameter to confirming constructional parameter, up to protracting overall drawing, needs at least half a year , and some modification has to make during the manufacture and assemble.The item of this paper sourced from a research project "development of centrifuge" arranged by the Planning Board of Anhui Province. In order to realize the rapid design of the centrifuge, a 3D-model is set up in this paper according to CBR theory, which is a parametric model with assembly-constrains. The design system is composed with four modules: type-choice module, technical parameter calculate module, parametric design module, choice of standard parts module, developed by means of ObjectARX on the platform of MDT. The user of this system can expediently input and amend the design parameters, and obtain a 3D-model of the centrifuge in a short time."The rapid design system for the centrifuge" is a beneficial application and a successful practice of the CBR-based rapid design technology and the re-develop technology on MDT...
