The report presents the results of research conducted at the G.S. Pisarenko Institute for Problems of Strength of the NAS of Ukraine. The research focuses on the development of methods and techniques for determining and enhancing the damping capacity of structural elements, vibration diagnostics of different types of damage in multilayer polymer composite elements, and the investigation of the impact of breaking cyclic symmetry on the vibrational stress of bladed disks in turbomachines. The main objectives of this research are to enhance the vibrational reliability of structural elements by improving their damping capacity, establish the scientific foundations for vibration diagnostics of various types of damage, analyze the vibrational stress of bladed crowns in turbomachines, and predict their stability limits under gas flow conditions.
