INVESTIGATION OF COEFFICIENTS OF CONSOLE BULL DAMPING FROM STEEL AND COMPOSITE MATERIAL
The article is devoted to the experimental determination of the damping coefficients of oscillatory systems on the example of a cantilever beam made of steel and a composite material based on carbon fiber reinforced plastic. The damping coefficient was determined at the first natural frequency, having a bending form of oscillations. Experimental measurements were carried out by a contactless method using a three-component scanning laser vibrometer in water and in air. The main attention is paid to the influence of water on the damping properties of the vibrating system under study.
