Research On Rapid Optimization Design Method For Forging Machine

With the development of globalization and the increase of competition in the market,a great change has happened to environment of modern enterprise.The competition of enterprises has emphasized more and more on the competition based on customers and time.On one hand the company should adequately meet consumer's demands in product manufacture,on the other hand the delivery should be as short time as possible and respond to varieties of product.Multi type&Small Batch rapid design module comes to the main model in production.We first introduce the present business situation and the research trend of forging machine both internal and abroad.The main problem in the forging machine design is the long period of design and so many raw materials costing.We focus on the research of rapid optimization design method for forging machine to achieve the quick-activity in design process and optimization in mechanical properties.Secondly we propose a customer-centric rapid design module based on current design model for equipment machinery such as forging machine.This module focuses on customer's need to make a correlate between requirement and concrete design. Multi-type & small batch rapid design module is addressed including product and rule's database in the whole product life cycle for the rapid information transmission. Then multi-type & small batch rapid design framework is build based on Product Data Management,integrating rapid modeling,rapid design and rapid optimization and the user interface.Subsequently,the relation between customer need and product performance is construct and calculation all dimension parameters from product performance.The change from customer need and product performance is based on altered DSM matrix. From matrix,array binary tree algorithm is run to divide the origin matrix to less relevant sub matrix for individual design.Parameter design model's input is the product performance,and product's dimensions are generated to drive the database to form 2D and 3D drawings.Information flow is critical for product design,and the process of rapid design software is as the same process of designing product.Hence,forging machine's UML model is created including use case diagram,class diagram,activity diagram and sequence diagram.The product tree is showed with XML language,whose nodes express the relationship between product and its parts.From XML document,product information is obtained with database,and the rapid plotting of drawings is realized.A rapid design system is build using above technology.This system divided the product design into several sub problems from customers' need.The parameters are counted in rapid parameter design module based on computational rules,and are the foundation of 2D and 3D design system.With PDM,the product tree,product BOM and quotation are realized.We also study the rapid quotation system of forging machine based on the rapid design system and PDM database.This system is divided into three parts:three dimension rapid quotation system including product's material's cost and manufacturing cost,two dimension rapid quotation system containing standard parts' cost,purchased parts' cost and common cost,and auxiliary cost quotation covering non machining cost such as environmental cost,labour cost and maintenance cost.All the price is stored in there sheet in PDM database.As a part,this task is sponsored by Chinese National programs for High Technology Research and Development.(No 2007AA04Z1A2).
