本文针对压气机转子叶片流固耦合问题，采用耦合平台MpCCI连接商业CFD软件FINE／Turbo与CSM软件ABAQUS模拟了设计转速下不同流量工况点的流固耦合问题，对比了流场定常计算与流固耦合非定常计算的结果，得到了叶片振动位移频谱振幅图以及效率和压比变化曲线。研究结果表明在失速点附近叶片振动对流场有显著影响，由此可以对压气机的颤振问题进行预测。
A Fluid-Structure-Interactive method was used to solve flutter problems in this paper. Main problems was Rotor blades for the Fluid-Structure coupling, through MpCCI platform and use the commercial software Turbo and ABAQUS do a coupling calculation. Obtained internal flow channel animation, under the different flow speed in the design, and flow field non-coupling and coupling calculations were compared. The results show that the blade vibration was effected significantly near the stall point. The analysis of compressor coupling can be used to predict the flutter.
