Research On Technology And Application Of Conceptual Design In Mechatrnoic System

The intelligence, flexibility and multi-functions of mechatronic system have become an important development direction of mechanical products with the fast development of mechatronic technology. Facing with increasingly international market competitions, enterprises will lose market competitiveness if they simply rely on copying foreign products or counterfeiting old pattern products. Only through the product creativity of mechatronics, can enterprises solve the key problem of new product design. Only through the product creativity, can enterprises solve the problem of surviving and developing fundamentally. However, about 75% of creativity is from the conceptual design in the process of product design, so research on design theory, method and application of conceptual design about mechatronic system have an important sense.The creation of design scheme is a higher-level creation in the conceptual design. Current scheme design of mechatronic system basically depends on designer's experience and design conception. Current method has not become a scientific design method. Or designer counterfeits the old pattern, it does not form an innovative design veritably. How to turn the experience-design into scientific design method that follows a certain theory becomes a key factor in mechatronic design.To solve the question above, beginning with function analysis, this paper studies theory and method of scheme creative design of mechatronic system systemically, which takes mechatronic system as a research object, and adopts the D&R (Decomposition and Reconstitution) theory and three-subsystem composition theory. Conceptual design process model of mechatronic system was developed and creative method that based on three-subsystem was founded.The object of conceptual design of mechatronic system is forming a scientific and effective expression. Function models about compose factors o f m echatronic system and its symbol expression method are established, which are based on function-cells and provide an effective measure for the expression of mechatronic system.The multi-levels and multi-objects evaluation items of the mechatronic system are presented according to the characteristic of mechatronic system. Illegible and integrated evaluation is developed.To validate the feasibility of the conceptual design method of mechatronic system, the case about the choose-machine of spring is developed. Beginning with the requirement analysis, the case shows the details of design scheme about the choose-machine of spring. Then the whole conceptual scheme is finished.At last, the research contents are summarized, and the questions that need research in future are put forward. A prospect about the next research contents is made out.
