摘要

All machines experience vibrations while they are in use, and these vibrations can shorten their lifespan considerably. Determining natural frequencies and describing the mode shapes of mechanical systems require experimental vibration analysis. Due to their self-lubricating properties and low coefficient of friction, polymer hybrid bearings are seeing an increase in use in some applications. This paper presents an experimental analysis of the vibration of polymer (PTFE) rolling contact bearings. A fast-fourier transformer (FFT) analyzer integrated with a rolling contact fatigue (RCF) testing apparatus is used to measure the vibration characteristics for the study. Data are continuously recorded in the time and frequency domains for various bearing samples under varying radial loading scenarios. The outcome demonstrates the relationship between vibration characteristics, applied loads and bearing performance. By keeping an eye on the vibration amplitude and frequencies, important information about the bearing’s state and potential failure modes can be obtained.
