采用MBD技术的液体火箭发动机三维模型设计

采用MBD(Model Based Definition)技术,以Pro/E和Intralink为协同设计平台,首次实现了液体火箭发动机的全三维数字化模型设计。通过将设计、工艺、材料和制造等相关信息包含在三维模型中,并将三维模型电子分发下厂,实现了用MBD模型完全取代传统研制模式中的二维图纸;同时基于MBD模型实现了三维仿真和装配过程分析,减少了方案反复。结果表明采用MBD技术的三维模型设计可显著提高产品研制效率,并为三维数字化制造奠定了坚实基础。

The 3D model design of liquid rocket engine using MBD technology

Using MBD(Model Based Definition)technology, the 3D model design of liquid rocket engine was realized on the platform of Pro/E and Intralink for the first time. The design, process, material and manufacture information were contained in the 3D model which were distributed electronically to factory and replaced the 2D drawings in the traditional development mode. Based on the MBD model, the 3D simulation and assembling process analysis were carried out, which decreased the scheme iteration. The research results indicate that the 3D model design using MBD technology can remarkably increase the development efficiency. Meanwhile, it can lay a solid foundation for the 3D digital manufacture.
