摘要
航空发动机外部管路系统的管路建模和流动分析分别在CAD和CAE软件中进行,在管路设计及改进时往往需在2种软件之间进行重复建模和数据传递,耗费大量时间与资源。为此,基于UG/Open API技术,通过对UG管路模型几何与拓扑信息进行研究,利用流体仿真软件FOCUSS-FS开发了UG NX3.0工作平台下的内嵌式管路流阻分析模块,实现了发动机管路建模时的实时在线流动分析,极大地提高了外部管路设计效率。
Pipe modeling and flow analysis of aeroengine pipe system were performed respectively in software of CAD and CAE.A great deal of time and resources were wasted in repeated data transmission and modeling between two kinds of softwares.The UG routing models and topology information were analyzed based on the UG/Open API.The inserted modules of fluid system resistance analysis in workbench of UG NX3.0 were developed by the flow simulation software FOCUSS-FS.The real-time on-line flow analysis of aeroengine pipe modeling was achieved,which increase the efficiency of pipe design.
