For stripe, targeted damping of resonance oscillations ceilings, foundations and other similar structures are currently actively used different vibration damping coating. To them can be attributed to the difficulty of applying them on requiring isolation structures, a significant mass of these coatings and their lack of effectiveness in the low and mid frequency range. In the 80s and 90s developed the use for these purposes mobile dampers – local wedge absorbers (LWA). Experimental and theoretical studies have shown the possibility of applying LWA for broadband damping of foundations and other engineering structures. In the article the algorithm of calculation of parameters of the LWA for their use on the plates. Also provides tips for choosing design petal LWA. The method of calculating the number and main characteristics of single and multileaf paintwork, mounted on plate structures.
