摘　　要：为综合分析叶片振动特征,以基础类库MFC为框架构建多种有限元软件(ANSYS及PATRAN)的融合平台,并开发相应的控制模块实现完整的流程控制。由所设计平台进行并行计算,获得压气机叶片的固有特性及其在气动激励诱导下的受迫振动特性。并行方式高效可行,且计算结果特征明显,表明平台具有良好的工程应用价值。In order to analyse blade vibration characteristics comprehensively, an computation platform based on MFC is designed with integration of different finite element softwares. Corresponding control modules are achieved for complete process manipulation. By using the computation platform, compressor blades＇ inherent properties and forced vibration response inspired by unsteady aerodynamic excitations are obtained in parallel. Efficiency of parallel mode as well as conspicuous characteristics of the simulation re- suits reveal the value of engineering application.
