Virtual Prototyping Growth Design, Mechanical Technology And Tools Development,

Based on the characteristics of Conceptual Design of product and the functions of the old version of design automatization system, DARFAD, the paper perfects the old functions and empolders some new functions of DARFAD system. The function module of Growth Conceptual Design of product is perfected. And the paper researches mechanics technology and design tools of product in product conceptual structure. Examples are given to prove the validity of the system.The paper completely researches and studies the developing status quo of the Conceptual Design of the mechatronic products at home and abroad, and discusses the problems in Computer Aided Conceptual Design of the mechatronic products. Theory of Decomposition And Reconstitution (D&R), Principle of Generalized Orientation and Mechanism of Growth Design are discussed. The concepts of Function Surface and Function Mode are given.The paper gives definition and sort of product prototype, and points out that visual behavior of product in computer is product visualization prototype during the process of conceptual design. The paper expatiates on the comparability between Conceptual Design of product and biology growth. On the basis of these basic theories and concepts, the paper brings forward the method of Growth Design of product visualization prototype which accords with Top-Down Design method, and researches the key problems which need to be settled in the Growth Design of product. The paper abstracts the basic cell, process control factor, growth method, integrity unification assurance of Growth Design and constructs the Growth Design model that is used in design system of product prototype, then accomplishes the system function module by the technology of 00 (Object Oriented). Product design based growth design makes the design process easier and more efficient, and makes the systemfit for the users who have no much professional knowledge.In mechanics technology, the paper researches how to get force and speed movement attributes according to function requirement of product design in conceptual growth design. According to this, we can calculate, analyse mechanics for product structure. And then, product structure can be carried on estimating of performance and decision-making of growth, and product structure can be guaranteed the optimization of growth.In addition, the paper develops some tool models that is used in design of product visualization prototype. They include the module of getting prototype, shell assembly, information modification of function surface, collaboration design and converting conceptual project to detail project (example part management and matching).At last, the paper expatiates on the functions and module setting, the development technologies and the running environment of product design system. An example of vice clamp is given to show the process of Growth Conceptual Design of product and mechanics technology. It testifies the validity and correctness of the theory and technology in the paper. The work in this paper has important references and guiding meanings for the study and development of mechatronic product CAD, especially CACD.
