N2 - Rotating Equipment Systems comprise three elements: the rotor, the bearings, and the support structures (housing, base and foundation). To predict the dynamic behavior of the system, it is possible to add the components in a global model. This procedure, however, is difficult to apply in complex structural systems. This work presents a methodology to generate a simplified dynamic model of the system, by means of dynamic characterization techniques. The method of Instrumental Variable Filter, "IVF", is used to define the model parameters (inertia, damping and stiffness matrices). Experimental data is obtained for two rotating equipment configurations comprised by a rotor, the bearing, and the supporting structures. IVF results are compared with an analytic Finite Element model and evaluated against measured unbalance response of the system. The methodology hereby presented may be useful for the field engineer, facilitating the analysis of dynamic phenomena of rotating equipments in maintenance and optimization studies.
