8 (495) 915-56-79, madam.ilinskaya@yandex.ru The work relates to finishing of turbomachine units and parts. The authors solved the problem of improving of reliability of the impeller strain measurement results. In this paper it is proposed a method of holographic interferometry, providing complete information about the shape and frequency of oscillations in absence of wheel rotation. It is given an example of the interaction of forced oscillations and self-oscillations of impeller in engine system.
