Research on the Three-Dimensional Process Design Method of Shipbuilding Based on MBD Technology

From two-dimensional engineering drawings, Computer-aided Design (CAD) technology to today's three-dimensional process design technology of Model Based Definition (MBD) based on feature representation and control, great changes have taken place in human engineering technology. With the applications of MBD technology in aerospace, machine-tool and other fields, it's also being actively explored in shipbuilding industry on engineering applications of the whole process of ship design and production under the background of intelligent transformation. After analysing the problems existed in process design of domestic shipbuilding enterprises, this paper firstly introduces a three-dimensional digital model of shipbuilding based on MBD technology. Then, a three-dimensional process design method is proposed in order to provide theoretical basis for the realization of three-dimensional process design of shipbuilding.
