Title: Damping Ratio Determination of a Cantilever Steel Beam
Keywords: damping ratio; dynamic model; free damping oscillations; int

Abstract: The aim of the present work is to model the damping ratio of a mechanical system by comparing experimental and numerical studies. The mechanical system consists of a cantilever steel beam and an attached mass – accelerometer. The sys-tem’s free damped oscillations were measured. The dynamic model of the system is discretized using the finite element method, and the equations are solved in a Matlab® environment. The best match between the experimental and numerical results is obtained within the frequency interval (related to Rayleigh damping) between the first and the third natural frequencies, at a damping ratio of 0.0069.
