This paper estimated the possibility of flow induced vibration in low-pressure compressor rotor with inlet guide vane.Through steady and unsteady numerical simulation

it was found that blade passage frequency of the guide vanes influences little on the vibration characteristics of the low-pressure compressor rotor.Moreover

because the intensity of vortex shedding in the wake of the guide vane is too weak

it's frequency has no influence on the vibration characteristics of the low-pressure compressor rotor.The computational result shows that both the design of airfoils and the location of installation are reasonable.
