Abstract
The results of assessment for the current technical condition of one of the complicated rotary-type machines with the use of a technology based on nonstandard methods of vibration monitoring and machine diagnostics developed at the Mechanical Engineering Research Institute of the Russian Academy of Sciences (IMASH RAN) are presented. Using the developed technology based on data obtained under perennial rotor unit operation, incipient defects have been revealed, and the process of changes in the unit vibration condition have been traced using S-discriminants. In addition, the time dependences of spectral amplitudes have been constructed to identify developing defects by calculating the stochastic interrelation between the time dependences of different vibration parameters, and an assessment of the current technical condition for such a unique machine as a moving neutron reflector has been carried out.
