Method for integrated designing screw pump

Abstract

Applying KBE, CBR etc. knowledge design, modularized and variable techniques, the method is built based on 3D CAD platform. The method includes following steps: (1) based on userí»s need, creating main parameters for preliminary design; (2) based on the said parameters, searching database to see whether there are products to meet userí»s need; (3) based on design scheme of functional module in the said products, searching structure instance of functional module in the said products to determine whether there is similar structure instance of functional module in the said products; (4) whether ANSYS finite element analysis is carried out for the said functional module; (5) based on structure of functional module, carrying out process planning, generating technological process sheet and operation sheet; using CAM subsystem generates NC machining codes for making module structure needed of using digital control machine-tool.

Description

technical field [0001] The invention relates to a design method of a screw pump, in particular to a design method of a screw pump by using a computer-aided design program. Background technique [0002] In the past ten years, due to the rapid development of advanced manufacturing technology, computer technology, network technology and communication technology, the simultaneous development of advanced design technology has been driven. The traditional CAD concepts are far from meeting the needs of current design. In recent years, advanced design theories and methods such as intelligent design and rapid design have injected new ideas into CAD. [0003] At present, the characteristics of rapid changes in international market demand and the more personalized market trends in the 21st century have promoted the development of rapid design and manufacturing technology. upsurge. Product rapid design and manufacturing is a new philosophy, its main purpose is to shorten the product d...

Problems solved by technology

This design method has great limitations, resulting in defects such as long design cycle, heavy weight of the designed product, and difficulty in controlling quotation errors.

[0006] Quite a few colleges and research institutions in China have researched the CAx integrated system of typical parts and standard parts. There is also research on the CAx of screw pumps, but the application effect of the system is not very satisfactory. After analysis, there are the following defects: Most of the CAD subsystems Based on the two-dimensional system, it just completed the work of "throwing the board" and did not give full play to the advantages of computer-aided design

Its shortcomings are as follows: (1) A large number of electronic graphics files exist in the computer without order, and are not well organized and managed, so as to be used as enterprise resources by new designs

(2) Due to the defects in the part structure expressed by two-dimensional drawings, CAD, CAE and CAM cannot be seamlessly integrated, thus limiting the promotion and application of CAE and CAM in product design and manufacturing

(3) The role of CAE in product design has not been paid attention to and brought into play
