Abstract: The use of low-modulus foam capable of intensive absorption of vibrational energy consists in reducing their number and amplitude under dynamic external influences. Computational experiments in the SolidWorks environment and field tests with the construction of vibrograms of damping flexural vibrations of a thin-walled cantilever beam have shown that volumetric damping with foam can be an effective means of damping free vibrations. The paper investigates the effect of damping on the resonant amplitude of forced beam vibrations. In the estimated design calculation, it is proposed to use an analytical expression to determine the logarithmic decrement of the foamed beam and the calculated data on natural frequencies obtained in a computer complex. A significant decrease in the resonant amplitude of the steady-state forced oscillations of the foam beam under bending is predicted. © 2020 American Institute of Physics Inc.. All rights reserved.
