Simulation and experimental study of the blade vibration monitoring (BVM) method based on blade tip timing Open
In the present paper, the blade vibration monitoring (BVM) method and the system products based on blade tip timing were studied and demonstrated in detail in the following four aspects: (1) Based on the finite elemental method (FEM) simul…
