Understanding of the Dynamical Properties of Machines Based on the Interpretation of Spectral Measurements and FRF

Abstract:

s: The paper deals with understanding vibration source, transfer path and vibration of cover sheets by using tools of condition monitoring an experimental modal analysis, namely spectral analysis and frequency response functions. The measurements were selected specifically to an electromotor, a rotor, a shock absorber and the cover sheets and outputs measured were interpreted with regard to achieving the goal of reducing noise and vibration of machines. In this paper is presented using FRF functions as a useful tool for the interpretation of measured data.
