The modern design method of the project of machinery

product and develop trend

Abstract:

According to the design of main thinking characteristics that the scholar carries on a hour of design of machinery product at home and abroad currently, generalize the design method of product project for systematize, structure modularization, is four type types according to the knowledge and intelligence of the product characteristic. Point out the characteristics of four kinds of methods and it is mutually the organic contact of, put forward the design calculator of the product project the diligent direction of the realization.

Preface

The science technically flies to soon develop, the product function request of increase day by day, complexity increase, the life period shorten and renew to change a speed to speed. However, the design of product, particularly the design way of the project of machinery product, then seem to be to lack the ability to do, can not keep up with the demand that the ages develop. Currently, calculator assistance product of design drafting, design calculation, process production, produce the programming have already more and extensively got with thorough of research, and beginning see result, but the product develop the computer aided design, CAD of early project but far far incapability satisfy the demand of design. For this, in reading a great deal of foundation of cultural heritage, the author generalized to tally up domestic and international design scholar to carry on project design adoption of method, and discussed of various method of organic contact and machinery product project design calculator realization of develop trend.

According to design scholar to carry on the main characteristic of method that the project design of the machinery product use at home and abroad currently, can generalize the modern design method of project to say four greatest types for the bottom.

1, Systematize a design method

The main characteristics which systematizes a design method is:See the design as a system which constitutes to°from some design main factors, each design main factor has independence, each main factor exists organic contact, and have layer, all design main factor combination after, then realization design the finished mission that system need.

Systematize design thought in 70's a professor to put forward from German scholar Pahl and Beitz, they take system theory as foundation, established the general mode of design and initiating design operate should have logical arrangement. The German engineer association establishes a standard VDI2221"technique system and the development of the product design a method" on the foundation of this design thought.

The progress mode of the project design of the machinery product of establishment, basically follow used the design method of German standard VDI2221.In addition, our country many design scholars still draw lessons from and quoted from while carrying on a product project design other progress nation of systematize design thought, among them what to have a representative BE: (1) customer's need Be product function the characteristic conceive outline, structure design and parts design, craft programming, operation control etc. of foundation, develop from the product of the macroscopic process set out, make use of the decoration method of the mass function, systematically customer need information reasonable but availably convert into technique target and operation that product develops each step to control the method of regulations.

(2)see the product as the life system on the organism layer, and ask for help from a life system theory, divide the line the design process of product function request layer, carry out the concept layer of the function request and the concrete design layer of the product. Adopted the sign abstract earth's surface of the life system diagram to reach the function request of product in the meantime, the function system of the formation product structure.

Because each designer research question of lay particular emphasis on of angle and consideration question spot dissimilarity, progress project design the
