METHOD OF DIAGNOSING OF ROTOR MECHANISMS Russian patent published in 2006 - IPC G01M7/02 G01M13/00 

FIELD: measurement technology.

SUBSTANCE: electric signal, which is proportional to object's vibration, is converted to spectrum. Amplitude components are memorized, the memorized values are compared with critical and estimation levels and after that condition of object is determined and indicated. Simultaneously with measurement and memorizing of basic signal, meanings of signals of accompanying factors are measured and memorized as well as temperatures of diagnosed object and environment temperature. Then the values are compared with corresponding critical and estimation levels with ones preset before. Diagnostics with diagnosis "not available for operation" is stopped when values of signals of accompanying factors simultaneously exceed critical levels and when components of main signal exceed estimation levels. Technical condition is determined and trouble-free operation time of object to be diagnosed is predicted when values of components of main signal and values of signals of accompanying factors do not exceed corresponding critical values.

EFFECT: reduced time; improved truth of results; higher reliability.
