Transformer Noise and Vibration Abatement
|
Passive vibration isolation solutions are commonly realized by placing a set of resilient elements
such as elastomeric (rubber), metal, or air springs between the isolated
objects and their foundations (bases). As shown in a
parametric study, such isolation systems (known as single stage mounting), do not address all
the requirements/concerns of an ideal isolation scheme, simultaneously; their effectiveness in addressing one isolation
requirement is normally at the expense of either not being effective in or
adversely affecting other requirements.
This is also true for the more elaborate 'double stage mounting' (also known as 'double mounting') scheme realized by mounting the isolated object on an auxiliary mass and isolating the auxiliary mass from the base using a second set of mounts.
Transformer Noise and Vibration Abatement |
Vibration isolation schemes are to 1) reduce the propagation of base vibration to the isolated object (machinery) and 2) abate the transmission of vibration energy of machinery to the base. Moreover, in vehicular/marine, industrial machines (such as mechanical presses), as well as seismic applications, isolation systems are also expected to lower the impact of shock from base to the isolated object and/or vice-versa. |

As an alternative to passive isolation solutions, the parameters of which are fixed and can not be changed once such solutions are put in place, one can use adjustable-passive (also known as semi-active) isolation schemes, such as
DEICON's
Computer Controlled Air Isolation System. Such systems allow for the in-situ adjustment of
the mounting parameters modifying the isolation system such that it best suits the instantaneous isolation requirement on hand.
