摘要: 对并行工程环境下航空发动机转子工作叶片基于特征的设计进行了研究和探索.在对叶片的结构特点进行分析的基础上,借助参数化特征建模技术,按照STEP(AP203/AP214)标准,建立了工作叶片的特征体系结构,并以此实现了一个三维实体特征建模系统.继而,在实现了模型由设计平台向分析平台的传递之后,成功地完成了模型的有限元静强度和振动分析.

Abstract: Feature-based aeroengine blades design is researched in concurrent engineering environment. Based on the analysis of the basic features of various aeroengine blades, parametric feature modeling technology and object-oriented method, feature architecture of aeroengine blades,and a 3D solid blade feature modeling system are developed according to STEP (AP203/AP214) on design platform LONICERA,which is an advanced integrated mechanical (CAD/CAM) design environment developed by Beijing University of Aeronautics and Astronautics. The data exchange with STEP is accomplished. A solid model is transmitted from design platform to analysis platform (MSC/ PATRAN/ NASTRAN), then strength and vibration analysis of a turbo-fan engine blade is carried out.
