摘　　要：为探究整机与部件仿真数据和测试数据的匹配性,基于MATLAB/SIMULINK、Python和通用商业CFD软件,开发了数据驱动的部件串行协同仿真技术,主要由航空发动机整机的集成仿真平台和部件串行协同仿真平台组成。其中,集成仿真平台采用模块化的方法对发动机部件建模,结合共同工作方程及边界约束条件,实现了发动机整机和部件特性的迭代模拟;发动机部件串行协同仿真平台采用自编程序结合底层求解程序,提出了重叠区域的交界面数据传递与处理方法,实现了部件间的串行仿真和边界迭代求解,完成了零维、三维仿真的耦合求解过程。以某小型涡喷发动机为研究对象,基于已有试验数据进行案例验证,计算结果最大误差不超过5%,表明集成仿真平台与串行协同仿真平台的准确性及工程应用价值。To explore the matching between the simulation data and test data of the engine and components,a data-driven serial collaborative simulation technology for aero-engine components was developed based on MATLAB/SIMULINK,Python and general commercial CFD software,which mainly consists of an integrated simulation platform for aero-engine components and a serial collaborative simulation platform.The integrated simulation platform adopted a modular approach to model the engine components,combined the cooperating equations and boundary constraints,and implemented the simulation of the whole engine characteristics;the serial collaborative simulation platform of engine components adopted a self-developed program combined with the underlying solver,proposed the data transfer and processing method of the intersection interface in the overlap region,finally implemented the serial simulation and boundary iterative solution between components,and completed the coupled solution of 0D and 3D simulation.Taking a small turbojet engine as the research object,the case verification was carried out based on available test data,the maximum error of calculation was less than 5%,indicating the accuracy and engineering application value of the integrated simulation platform and serial collaborative simulation platform.
