vibrations

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 harmonica, a mobile phone, or the cone of a loudspeaker.
In many cases, however, vibration is undesirable, wasting energy and creating unwanted sound. For example, the vibrational motions of engines, electric motors, or any mechanical device in operation are typically unwanted. Such vibrations could be caused by imbalances in the rotating parts, uneven friction, or the meshing of gear teeth. Careful designs usually minimize unwanted vibrations.
The studies of sound and vibration are closely related. Sound, or pressure waves, are generated by vibrating structures (e.g. vocal cords); these pressure waves can also induce the vibration of structures (e.g. ear drum). Hence, attempts to reduce noise are often related to issues of vibration.

    Washing machine vibrations

    Hey guys. What's the best way to absorb washing machine vibrations? It's currently on a suspended floor and sounds like a rocket take off. I've got lots of polystyrene I could put underneath to absorb vibrations or any other material you could recommend. Many thanks

    HeatraeSadia Electromax vibrations after service: Is this an EV pressure issue?

    Our HeatraeSadia Electromax boiler has just been serviced. Since the service we get a lot of vibration from the system each time the hot water is run after the system has been heated up. After some investigation and correspondence with the service engineer we concluded that it was probably...
