Abstract

Based on Hilbert transformation technique, the time domain test method for nonlinear damping of a fiber-reinforced composite thin plate with amplitude dependence was studied. Firstly, by using Hilbert transformation technique, the expression for nonlinear damping of the composite structure system with amplitude dependence was derived, the theoretical principles of acquiring nonlinear damping parameters through time domain measurement were clarified. Then, the algorithm was written with MATLAB and numerical examples were used to prove the correctness of the algorithm. Finally, the reasonable and standard test procedures were summarized and applied in the real measurement of a TC500 carbon fiber/resin composite thin plate. It was shown that the proposed method can effectively acquire its damping parameters at different decay instants, so it can be used to quantitatively evaluate nonlinear damping characteristics of composite structures with amplitude dependence under different excitation amplitudes and frequencies.
