Experimental Determination of Non-Ideal Structural Boundary Conditions Based on Spectral Element Model

Abstract:

In this paper, experiments are conducted to determine the non-ideal boundary conditions (BCs) of example beam structures. The spectral element (SE)-model is used for the beam structures, and the non-ideal BCs are represented by the frequency-dependent effective boundary springs. The boundary spring constants are then determined from the measured FRF-data. It is shown that the vibration responses analytically predicted by using experimentally identified BCs are very close to the measurements.
