摘要
针对航空发动机泵类及调节器产品结构复杂、孔类特征多、建模过程繁琐、几何信息表达与传递困难等特点,通过对壳体模型数据集及结构的深入探索和研究,在UG平台上开发出适用于MBD技术的知识融合系统,将知识工程、产品标准规范等抽象、分散知识更加形象和集中地表达。实现了设计模式由"基于经验和试错驱动"向"基于知识组件驱动"的转变,从而形成航空发动机复杂产品的创新MBD设计模式。此模式在某国家级重点型号中得到深入应用,提高了复杂壳体产品的设计效率和质量。
Due to the complex structures of aeroengine pumps and governors,3D modeling,geometric information expression and delivery are more difficult.In order to solve these inconvenience,knowledge integration system seems to be a better method to choose.Practice of knowledge integration system is mainly introduced,which is developed on UG platform and suit for MBD technology.Through the deep study of housing model data set and structure,knowledge integration system abstracts the scattered knowledge,standard,specification,using a graphic way to express.It makes the design mode change from ＂based on experience＂ to ＂based on knowledge＂.The knowledge integration system is widely verified at several products,it shows complicated housing design efficiency and quality can be largely improved.
