| Abstract: | The results of vibrational tests of aluminum alloy samples with different filler content are reported. The resonance frequency, the frequency and transmission characteristics, and the dissipation parameters were determined for identifying and certifying the samples. A specialized vibration stand was designed. The influence of the excitation amplitude on the amplitude-frequency and phase-frequency characteristics of the harmonically and resonantly excited samples was analyzed. It is shown that various methods exist for estimating the damping characteristics and the nonlinear effects in test samples. |
