摘要
以航空发动机涡轮叶盘结构为研究对象,构建了涡轮叶盘自上而下的主模型控制结构。通过实施几何约束、拓扑约束和关联表达式,实现了部件模型的参数化,并进行了基于多学科优化设计的语境模型分析。研究了多学科优化设计中涡轮叶盘主模型的实现方法,以及优化中模型数据的集成控制。
The structure of the aero-engine＇s turbine disk and blade are taken as the study objects.It is built for the top-down control structure of the master model.The parameterization is realized by geometric constraints,topological constraints and connected expressions.Context models are analyzed based on Multidisciplinary Design Optimization（MDO）.The master modeling method of the turbine disk and blade is studied in MDO.The model data can be integrated and managed uniformly in MDO with the application of master model.
