摘　　要：介绍一种易于应用到工程实际中的ANSYS Workbench仿真方法。以CFM56-5B发动机扇级叶片的振动特性分析为例,通过Mechanical模块和CFX模块的耦合计算,详细阐述了ANSYS双向流固耦合振动仿真的方法以及在仿真过程中需要注意的事项,为分析复杂的非对称翼型截面的预扭叶片及其接近工程实际的流体场动力学振动问题提供理论参考。A simulation method of ANSYS Workbench which is easy to be applied in engineering practice is introduced.Taking the vibration characteristic analysis of CFM56-5B engine fan blades as an example.The simulation method of ANSYS two-way fluid-structure coupling vibration and the matters needing attention in the simulation process is described in detail by coupling the Mechanical field with CFX field.It provides a theoretical reference for the analysis of complex asymmetric airfoil cross-section pre-twisted blade and the dynamic vibration of the fluid field which is close to the engineering practice.
