The paper discusses the effectiveness of currently used methods of surface damping of bending vibrations for thin-walled structures. The special features of surface damping of vibrations using a free and constraining layer damping are analyzed from a physical point of view and practical application. A combined damping coating is proposed, which allows integrating the positive qualities of both of the above methods. An experimental comparison of the effectiveness of the known and proposed methods for damping of bending vibrations of thin-walled structures is made using the method of free damped oscillations.
