In the past, unwanted machine vibration could be isolated by placing the equipment on top of cork or felt. However, with greater expectations and expanded knowledge, such methods of isolation are now inadequate, both in large building structures and in the general industrial environment.
In building construction, improved design allows lighter but inherently more flexible structures to be used. At the same time, increasingly powerful air-conditioning and auxiliary equipment is needed and may often be installed in upper level plantrooms. Equipment vibration can therefore be a major problem in such flexible structures. Similarly, in general industry, the output of vibration producing equipment is increasing whilst the community and workforce demand improved living and working conditions, free from vibration or structure-borne noise. Both situations require engineered vibration control systems which give predictable results appropriate to the surrounding environment.
