METHODS OF ESTIMATION OF COMPLEX FREQUENCY DESCRIPTIONS OF LTM AND BRM BEARING KNOTS

METHODS OF ESTIMATION OF COMPLEX FREQUENCY DESCRIPTIONS OF LTM AND BRM BEARING KNOTS

The method of studying bearing units (ball bearings) of handling and construction of road machines in the low-frequency range of vibration-acoustic signal is presented. It includes: the choice of the method and place of vibration sensors installation, vibration signals registration modes, instrument...
