The bearing faults create impulses and results in strong harmonics of the fault frequencies in the spectrum of vibration signals. These fault frequencies are sometimes masked by adjacent frequencies in the spectra due to their little energy. Hence, a very high spectral resolution is often needed to identify these frequencies during a FFT analysis.

7-12-2018 · One of the most annoying things that can happen to a car is picking up some kind of vibration. While a vibration is not usually a safety issue unless it becomes very bad, a shaking car is no fun to drive. Furthermore, it can be frustrating to diagnose which of the many complex components that govern the car's contact with the road is causing the steering wheel shimmy.

Vibration - WikipediaDeze pagina vertalen

Vibration is a mechanical phenomenon whereby oscillations occur about an equilibrium point.The word comes from Latin vibrationem ("shaking, brandishing"). The oscillations may be periodic, such as the motion of a pendulum—or random, such as the movement of a tire on a gravel road.. Vibration can be desirable: for example, the motion of a tuning fork, the reed in a woodwind instrument or ...

Vibration Analysis of a Roller Bearing With a .

Vibration performances of roller bearings are greatly affected by various localized defects. Thus, it is very important to analyze vibration characteristics of the roller bearings with the localized defects. In this paper, a nonlinear dynamic model is developed to formulate the effect of a localized defect on the vibration characteristics of a cylindrical roller bearing (CRB). A bump defect is ...

Bearing (mechanical) - WikipediaDeze pagina vertalen

A bearing is a machine element that constrains relative motion to only the desired motion, and reduces friction between moving parts.The design of the bearing may, for example, provide for free linear movement of the moving part or for free rotation around a fixed axis; or, it may prevent a motion by controlling the vectors of normal forces that bear on the moving parts.
