What is Vibration isolation?
[[File:Chainsaw spring mount.jpg|thumb|A [[saw]] isolated from its [[engine]].]] '''Vibration isolation''' is a system of devices to decouple a mechanical or structural object from its vibrating supports.<ref>{{Cite web |url=http://physics-animations.com/Physics/English/spri_txt.htm |title=Passive and Active Vibration Isolation Systems |access-date=2010-08-14 |archive-date=2007-02-04 |archive-url=https://web.archive.org/web/20070204101728/http://physics-animations.com/Physics/English/spri_txt.htm |url-status=dead }}</ref> For example, the handles of the saw presented in the right photo are separated from the engine and cutting bar to reduce shaking for the operator. Here, the spring mount is a part of this vibration isolation system. When the targeted object is rather heavy (e.g. [[building]], [[bridge]] or the like), vibration isolation may be called [[base isolation]]. Vibration isolation is a branch of protective techniques known as [[vibration control]]. ==History== From the very beginning, the theory of vibration isolation, in general, and of base isolation, in particular, rested on two pillars: ''heavy damping'' and ''frequency separation''. Unfortunately, nobody paid any attention that the heavy damping was a sort of a strong connection between a ''substructure'' and ''superstructure'', and that the idea of decoupling them with the help of such connections was of no good. ==Related pages== *[[Damping]] *[[Vibration]] *[[Earthquake protector]] ==References== {{commons category|Vibration isolation}} {{reflist|2}} [[Category:Mechanics]] [[Category:Mechanical vibrations]]
