The Overall Program Design Of Mechanical Products And Applications

The design of mechanical product outline schemes is an important part of the product developments; it has a crucial influence on the detailed design, manufacturing, sales and other areas. It directly decides the product quality, the performance, the cost, the reliability, the security and the environment-protective, and the defects which it produces are unable to be made up by the following design processes. At the same time, the period of scheme design has the least restrictions to the designers, so the designers can fully display their experience, their wisdom and their creativity. And it decides the degree of product innovation. Therefore, improving the quality of product scheme design is the most important way to enhance the market competitiveness of the mechanical products and gain the superiority of market competition.This paper embarks from the general processes of the designs of product outline scheme. On the basis of the systematic study of the mechanical design of products in principles, contents, methods, and the evaluation and decision-making of scheme and other aspects, the study puts the economy and technology together during the process of overall scheme design with the new requirement of current market economy, especially integrates the person-machine-environment system design and modeling design with outline scheme design. So it consummates the outline concept design system. In the appraisal stage, a kind of method which can reduce the influences of subjective factors is used, that is a method of fuzzy evaluation based on analytic hierarchy process (AHP). In order to confirm the correctness of the above idea, it gives an example of the outline project design of dish-rolling grinder (science and technology research project in Henan Province, and the project number is 0496050803) .The chosen precept after detailed design is put into product, and the energy consumption of this milling machine is low, and the output is very large, so it can bring considerable economic efficiency to the enterprise. This is a successful product design case. And the theories and methods described in this paper are made sure to be correct and feasible.The research to outline scheme design in this paper has highlighted the importance of theefficient and technological factors. And it is more accordant with the product designcharacteristics, under the market economy conditions. So this paper is very useful to guidehow to apply the theory of mechanical products overall concept design in the actualproduction.
