Prestressed Multilayer Structures from Polymer Composites for Vibration and Noise Control of Aircraft

An approach to creating compact and miniature infra- and low-frequency vibration isolation systems based on layered composite elastic elements with adjustable negative and quasi-zero stiffness is presented. New problems of modeling the given parameters of the stiffness and bearing capacity of elements of certain geometry under combined loading have been solved by varying the structure, elastic properties, and arrangement of layers and controlling the local mobility of the binder. The correctness of the approach is based on the results of experimental design and research of system models. This approach can qualitatively change the solution of a number of critical problems in vibroacoustics of aviation and other advanced engineering.
