Diagnostics of the state of machines by vibration characteristics

Abstract

Based on studies of vibrations in metal-cutting machines, it is shown that the use of modern vibration measuring equipment and sensors, in particular three-component vibration sensors, increases the accuracy of measurements, significantly expands the possibilities of vibration analysis, allows to assess the trajectory of oscillatory motion, to obtain attractors and to diagnose on this basis the presence and magnitude of imbalances, the quality of installation and condition of bearing assemblies and the bearing system of machines.
