针对数字化设计技术的定义分析了其特点，阐述了当今数字化设计技术研究的热点——计算机辅助概念设计、知识工程、虚拟原型技术；探讨了机械产品数字化设计技术的研究现状及未来的发展趋势，即突出产品创新设计、重视虚拟现实技术、强调产品协同设计；数字化设计技术作为国家中长期科学技术发展规划优先扶持的主题，其应用将会使传统的农业机械设计制造技术发生革命性的变化。

To date, conventional design is gradually converted to modem design. As a synthetic technology, the digitized design technology contains the latest technologies in modem 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.
