摘　　要：试车台架参数化设计是提升航空发动机试验效率的有效手段。通过对航空发动机高空模拟试车台架进行分析,确定其典型结构并提取结构特征、关键参数和约束关系。按照功能对试车台架进行模块化划分,建立零组件的参数化模型和数字样机。运用WAVE技术、模块化技术和参数化设计技术建立试车台架参数化设计系统,实现了试车台架模块化、半自动化、全三维快速设计。实际应用表明,建立的参数化设计系统可有效降低台架返修次数,减少工作量,缩短设计周期和提高设计效率。Parametric design of aero-engine altitude simulation test bed is an effective means to improvethe test efficiency. By analyzing the aero-engine altitude simulation test bed, a typical bed structure was de-termined and its structural characteristics, key parameters and constraint relationships were extracted. Thetest bed was divided in modular according to functions, and parametric models and three-dimensional digi-tal mockup of components were established. A parametric design system for the test bed was established byWAVE technology, modularization technology and parametric design techniques. Thus a modular, semi-au-tomated and full three-dimensional rapid design of the test bed was realized. Practice results show that theparametric design system can effectively reduce the workload, shorten the design period and improve designefficiency.
