Research On Digital Design System Of Scraper Conveyor

With the development of fully mechanized mining technology,the scraper conveyor,as the core equipment in mine transportation,show a diversification of product series and complication of structure function.By learning and absorbing foreign advanced design concepts,greatly promoted the development ability of scraper conveyor,but the design process priority based on manual calculation analysis,there are so many defects,such as design efficiency low,repeated design.design process repetitive.Aimed at these drawbacks,the scraper conveyor designing by a domestic mining machinery manufacturing enterprises as the object,the modern design theory and knowledge engineering into existing scraper conveyor in the process of research and development,completed the digital design system of scraper conveyor,the specific work is as follows.Summary of traditional design process and method of scraper conveyor,and integrated into the computer applications for new product development.Finite element analysis of structural strength of the scraper conveyor of key parts and components,the analysis process and data integration,help designers effectively using CAE data.To establish components parameters model of the scraper conveyor in UG,get the digital prototype through bottom-up assembly,the key components of the design parameters,can be completed parts revision and two modeling work quickly and accurately.Building a knowledge base for the design knowledge and examples,through the human-computer interaction interface,realize the data and parameters of the fast access,browse and query functions,design knowledge and experience sharing.To establish the system help files,assist designers to quickly master the use method of the system,improve the efficiency of design.With modern design theory and knowledge engineering theory as the background,using mine engineering technology,database technology,CAD/CAE customized development technology and knowledge engineering techniques,using UG/NX 7.5 as the platform,based on the class of Microsoft VS 2010(MFC)and NX/Open API as the development tool,combined with SQL Server database,develop a scraper conveyor digital design system.a set of conceptual design,parametric design,CAE analysis,knowledge management in one of the scraper conveyor digital design system,including concept design,parametric design,CAE analysis and knowledge management.The design system can help improve the design efficiency of scraper conveyor,reduce production cost,shorten the development cycle,promote the application of enterprise knowledge innovation,improve the design environment,enhance the competition ability of the product in the market.At the same time,it can promote the establishment and development of application of CAD/CAE technology,accelerate the technical modification of the scraper conveyor application enterprise.
