摘　　要：为了创新液体火箭发动机研制模式,提高数字化设计与制造水平,某液体火箭发动机研制采用了三维数字化协同设计模式。采用自顶向下设计模式和多层骨架方案,建立了发动机骨架模型,实现了无纸化接口协调;基于模型定义技术,将设计、工艺、材料和制造等相关信息全部包含在三维模型中,用三维模型完全取代了传统设计模式中的二维图纸;通过建立IPT开展协同设计,工艺人员并行介入产品设计流程,提前了解产品结构、开展工装设计和工艺模型设计。研究结果表明三维数字化协同设计可显著提高发动机研制效率,缩短研制周期,并为三维数字化制造奠定了坚实基础。In order to innovate the development mode of the liquid rocket engine, and improve the lever of the digital design and manufacture, the 3D digital collaborative design mode was used in the development of liquid rocket engine. The engine skeleton model was established with the top-down mode and multi-skeleton scheme, with which the paperless interface coordination was realized. Based on the MBD （model based definition） technology, the design, workmanship, material and manufacture information were contained in the 3D model which replaced the 2D drawings in the traditional design mode. The technologists in IPT （integrated product team） organized for the collaborative design intervened concurrently in the product design process, so that they can know the product structure and carry on the design of tooling and technical model in advance. The research results indicate that the 3D digital collaborative design can remarkably improve the development efficiency and shorten the development cycle. In addition, it lay a solid foundation for the 3D digital manufacture industry.
