Abstract: The model of a centrifugal machine is developed, critical speeds are specific by methods of Dunkerley and Krylov at a casual defluxion from revolution axis of center of mass, the analytic form of a function of casual exhausts of oscillatory process for a centrifugal machine - functions of the theory of vibration reliability is introduced-, the median number of exhausts in unit of time for a casual defluxion of center of mass from revolution axis of a centrifugal machine is designed. It is exhibited, that at designing or optimization of a design of a centrifugal machine from the point of view of a reliability theory the design with smaller number of exhausts in unit of time is more preferable.

Key words: сentrifuge critical speed vibrational reliability method of Dunkerley method Krylov the median number of exhausts oscil-latory process
