Development Of A Rapid Design System For Large Gantry-type Digital Control Pipe Machines

With the rapid development of Chinese oil-gas transportation industry,upgrade of pipe-making facilities is becoming rapid,efficiency design and quality design of new products have been the important part of enterprise competitiveness.As a new product,the design,analysis,modeling of structural similarity of gantry CNC pipe-making machine increase repetitive work,which affect the time and quality of new product seriously.In this paper builds the rapid design system of gantry pipe-making machine on account of ever-increasing product demand and the low design capacity and efficiency.Firstly,the paper introduce the building methods and key technology of rapid design system and the classification scheme of pipe-making machine parts.Based on the requirement system of structure behavior analysis and automatic modeling,the prototype of the rapid design system is proposed.Secondly,a standard database including products,parts and interfaces is built.According to the fact that 3D mode and engineering drawing is the important method for the design reducer,automatic modeling and adjustment of engineering drawing of pipe-making machine has been analyzed.Thirdly,the dissertation has made study on software implement structure behavior analysis through APDL and structure optimization scheme selection for pipe-making host basing on TOPSIS comprehensive evaluation method.Finally,main functions of the system are operated through instance,which meet the design demand and improve the design efficiency.After a period of commission and operation,the rapid design system meets with structure of gantry pipe-making machine,which has some reference values for design and analysis of large gantry facilities.
