Vibration-based estimation of beam boundary parameters
Two methods are suggested for using measured vibrations to estimate linear boundary stiffness and damping for beams, while simultaneously estimating axial tension. Estimation is performed by fitting model boundary parameters to measured modal vibration data. The methods are validated using simulated and experimental data, and shown to be accurate when boundary parameters are not extreme, i.e. representing either zero stiffness or compliance.
