Abstract�� Rotor blade forcing response problems due to the wake of front vane row was analyzed. A transient analytical method was presented for blade forcing response. Then displacement and stress could be predicted. The analysis of three-dimension unsteady flow field was performed with NUMECA to provide the wake influence force and the pressure was introduced into calculating structure dynamics(CSD). Structure analysis was performed by finite element package ANSYS using transient analysis type. Force boundary condition was written with ANSYS parametric design language(APDL), a scripting language for ANSYS. The displacement and stress under different rotate speed were calculated. Then compared them with Compbell method. For transient analytical method, whether flow field or structure analysis were both presented with well-rounded software, so it’s easy for using in engineering field.
