Model Based SHM - Rotating Machinery Application
The paper presents application of the model based diagnostic method for early detection of faults in rotating machinery. The applicability of modal model identification techniques for structural health monitoring of rotating machinery for linear and nonlinear cases is presented. The method based on both operational and experimental (with specially designed active experiment) is discussed. The approach including mapping of nonlinear system to time varying linear one is employed. The theoretical formulation of the method and experimental verification on laboratory rig is shown.
