The benefits of vibration screening
Vibration screening devices (such as vibration pens or bear- ing checkers) provide quick feedback of the equipment con- dition by looking at the overall levels of vibration or bearing condition to understand whether there is a problem, instead of analyzing vibration in-depth with a spectrum.

What Is Natural Frequency? - ThoughtCo
Updated December 03, 2018. Natural frequency is the rate at which an object vibrates when it is disturbed (e.g. plucked, strummed, or hit). A vibrating object may have one or multiple natural frequencies. Simple harmonic oscillators can be used to model the natural frequency of an object.

Objectives Transportation of goods on railways is increasing and the majority of the increased numbers of freight trains run during the night. Transportation noise has adverse effects on sleep structure, affects the heart rate (HR) during sleep and may be linked to cardiovascular disease. Freight trains also generate vibration and little is known regarding the impact of vibration on human sleep.

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 ...
