Technical facilities are intended for diagnosing and controlling the technical condition of tribomechanical systems and friction joints in mechanisms provided that systems function without disassembly. Technical facilities ensure controlling noise and vibration parameters, lubrication operating modes and triboemission. Programming software allows to acomplish tribodiagnosing, i.e. to estimate friction joints parameters and to predict their change, the operational conditions and the mechanism construction peculiarities taken into consideration. These facilities may be employed in aviation, electrical machine building, power engineering (atomic engineering inclusive), instrumentation and others. Special models for diagnosing the system technical state as well as models of parameters changes are required for methodical provision. Thus, there exit two types of characteristic processes in a generalized model: rapid ones, i.e. noise, vibration and fluctuations of operational parameters, and slow parameters change. Rapid processes define the quality of functioning at a given moment of time while slow ones account for parametric system reliability. By monitoring the changes in these vibration properties, impending structural failure can often be detected before equipment has been damaged, personnel have been endangered, and costly machine downtime has been incurred. The noise and vibration sensor is a traditional device, the lubrication condition sensor is based on an electro-physical method and it is an original one, the triboemission sensor is analogous to that of acousto-emission but it operates in a specific mode. The principal novelty factor is a combination of measurements from three sensors into one infromation flow possessing definite synchronization. The diagnosing is conducted on the basis using Wavelet Analysis transform.
