IMPACT OF SELECTED OPERATIONAL PARAMETERS ON MEASURES OF TECHNICAL CONDITION OF ROLLING BEARINGS IN MEANS OF TRANSPORT BUILT BASED ON ANALYSIS OF VIBRATION SIGNALS

Abstract

This article presents an innovative method of diagnostics of rolling bearings used in the bearing nodes of motor vehicles, with the use of a prototype specialist stand. The tests were carried out based on a developed research plan, which included the impact of damage to the bearing and tyre of the vehicle, as well as the vehicle speed. Vibration accelerations were recorded in three measurement axes. Signal spectra were created based on the time courses of the vibration signals and were further analysed. The presented method is aimed at detecting excessive wear of rolling bearings in wheels from its early period.
