应对现代制造业产品数字化、智能化的发展趋势,各制造企业对三维数字化设计和制造技术的研究方兴未艾。基于模型的定义(MBD)作为全过程数字化设计解决方案,在国外先进企业如波音公司中得到了广泛应用,收效显著。三维模型定义的效益已经被世界知名公司和机构反复验证,例如波音、空客、庞巴迪和通用等。其中美国海军航空作战中心Lakehurst飞机分部2013年的试点估计,年度经费可以节约24%,约合2100万人民币。MBD定义将传统模式下三维设计模型、工艺模型、二维
In response to the digital and intelligent development trend of modern manufacturing products, the research on three-dimensional digital design and manufacturing technology of various manufacturing enterprises is in the ascendant. Model-based definition (MBD) as the whole process of digital design solutions, advanced enterprises in foreign countries such as Boeing has been widely used, significant results. The benefits of the 3D model definition have been repeatedly validated by world-renowned companies and institutions such as Boeing, Airbus, Bombardier and General Motors. In 2013, the pilot of the Lake Navrst Aircraft Division of the U.S. Naval Air Operations Center estimated that the annual funding could be saved by 24%, or about 21 million yuan. MBD defines the traditional model of three-dimensional design model, process model, two-dimensional
