FIELD: machine engineering.
SUBSTANCE: invention includes the measurement of vibration parameters of the machine housing and building trends of their changes over time. The trend rate of change in estimate vibration parameters and values used in conjunction with the latest rates as diagnostic features of the machine. When trending vibration parameters distinguish the upper and lower envelopes of its maximum and minimum values. By enveloping determine the rate of change and the spread of vibration parameters and the latter is used as a diagnostic feature to assess the technical condition of the machine.
EFFECT: higher reliability of the diagnosis on the trends of vibration parameters of the machine housing.
