Vibroacoustics of machines is the main scientific direction, it includes the development of physico-mathematical models of processes of excitation and propagation of vibrations in ship mechanisms, machines and structures. Development of methods for calculating forced oscillations and sonar radiation of the submarine's hull modeled by a finite elastic cylindrical shell in a liquid. Vibroacoustics and vibration monitoring of machinery. Investigation of hydroacoustic fields of marine mobile objects (atomic submarines).
