FINITE ELEMENT MODELING OF BEAM AND ITS VALIDATION USING EMA
Keywords:
Modeling. Beam, Finite ElementAbstract
An vibration based analysis measurement requires data on the nyquist plot from a setup. It is necessary to acquire the impulse response resulting from the excitation's free decay in order to undertake a time-domain analysis, or to obtain the affect from ambient excitations. As there are several ways to get signals and do the measurement, the FRF of such beam is measured using one of the simplest and most adaptable techniques, and the procedure is described in this chapter. This approach involves exciting the structure with a particular input signal at a predetermined position, and measuring the force and the structure's reactions to that force. which, as a consequence, gives information about a particular set of FRFs, which may then be examined further to carry out modal analysis and produce the modal model that represents the structure.
