The Research On Modular Design Of Automotive Panel Die Based On Knowledge Engineer

The rapid development of automotive industry and speedy update of new automotive model require the automotive manufacturers to develop high quality automotive in short period. However, the manufacturing of panel, to a great extent, restricts the development of new automotive model. The automotive panel die is a important technological equipment of automotive panel manufacture. So the method that shorten the panel die'design period would be important for abbreviating the development period of whole vehicle body and accelerating the update speed of automotive shape(model)In automotive panel die design, the application of professional design software is an effective method to shorten the design period of automotive panel die. The fast development of hardware and software of computer provide qualifications for the development of die professional design software and its higher exploitation. It is one of the mainstreams to introduce Knowledge-Based Engineering (KBE) technology, on which international research focus, into the process of automotive panel die design.On the basis of studying the structure of automotive panel die, the following research works of modular design of automotive panel die have been done under the guidance of KBE technique.First, based on studying the theory of the modular design, the module partition and combination methods of automotive panel die are analyzed.Second, with the introduction of KBE technology to modular design of automotive panel die, the method of acquiring, accumulating, updating and searching knowledge is explored, with the implementation method of modular design of automotive panel die studied.Third, the architecture of panel die's modular design system based on KBE is studied. The modeling method of modules and assembly method among the modules are also analyzed. Furthermore, with the foundation of automotive panel die module example database, the modular design system of automotive panel die based on UG software is developed.The modular design system of panel die can make rapid response design of automotive panel die come true. Applications of the design system have proved that it can reduce the workload of designers to a large extent, improve the efficiency and veracity of panel die design, reduce the development pried of panel die design and enhance the competitive power of enterprises; it shows that the system has high practicality.
