Digitized Design Technology and Its Application in Agricultural Machinery Design

To date,conventional design is gradually converted to modern design.As a synthetic technology,the digitized design technology contains the latest technologies in modern design,and as the premise of it.In this paper,the property of digitized design technology is analyzed based on the definition of it and the present research hot spots of digitized design at home and abroad,namely,CACD,KEB,VP are given.The digitized design technology being used in machinery(taking agricultural machinery as example) and its development trend in future,which gives prominence to products innovation design,thinks much of virtual reality technology,and emphasizes cooperative design and manufacture,are also discussed.The application of digitized design will lead to revolutionary change in agricultural machinery design and manufacture.
