The Rapid Design System Of The Front Axle Of The Automobile

Today,the competition of market is becoming more drastic and how to shorten the developing cycle of products and how to enhance the success ratio of the product design have become a pressing matter at the moment for each enterprise. The paper mainly discussed the technology of the rapid design of products. Furthermore,the writer has successfully developed "the rapid design system of the front axle of the automobile" based on the theory of the CBR-based variant design.The primary object discussed in the present paper is the front axle of the automobile made in Jianghuai Automobile Corporation. In order to realize the rapid design of it,the writer has setup a part database which covers the 3-D model,the drawing and the material database of the representative parts. Using the idea of top-down design,the writer built up 3 ways to complete the variant design:dim-questioned,feature-controlled and database-visited of standard parts. By means of FEA module,the writer can produce the FEA model of the original program and get results of the analysis as well. Finally,the drawing,the BOM and the list of the part property of the final program will be produced through the module of detailed design.The system was developed by means of Pro/toolkit on the platform of PRO/E. Users can realize the rapid designing on the basis of the design template of the front axle and the command of the special menu system.The research is a beneficial application of the technology of CBR-based variant design on the platform of PRO/E and is also a successful practice of the development technology on PRO/E.
