Mechanical and electrical product design standard selecting method

Abstract

The invention provides a mechanical and electrical product design standard selecting method. By the mechanical and electrical product design standard selecting method, the problems that design parameters and parameter standards are excessive in a product design process, the design parameters are coupled to one another, so that mechanical and electrical product design parameter standards are selected complexly or are selected by experience are solved. The mechanical and electrical product design standard selecting method comprises the following steps of establishing a product database and a knowledge base by using a system through an information technology; establishing mapping of a product performance parameter to a product design parameter; establishing a various-target and multivariable mathematical programming model on the basis of the mapping; and selecting a product design parameter standard. By the product design standard selecting system, standard selection complexity and requirements on design experiences of design workers are reduced in a product designing process, accuracy and scientificity of product design standard selection are improved, and demands on informatization of product design standard selection are met.

Description

technical field [0001] The invention relates to a data processing method suitable for computer-aided design to realize specific functions, in particular to a method for selecting design parameter standards of electromechanical products. Background technique [0002] The product design process involves a number of domestic and foreign technical standards, mainly including the standards formulated by the International Organization for Standardization (ISO), the International Electrotechnical Commission (IEC) and the International Telecommunication Union (ITU), as well as the standards formulated by international organizations recognized and published by international standards , In addition, it also includes some advanced industrial national standards, such as American National Standard ANSI, German Industrial Standard DIN, British National Standard BS, Japanese Industrial Standard JIS, etc. [0003] In the case of multiple technical standards for part design parameters, there...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is that there are too many design parameter standards in the product design process and there is no unified standard selection method, which leads to complex selection process, experience-based and long selection cycle of design parameter standards, low efficiency, poor versatility, and failure to meet information requirements. the question of needs
