CFM-header

Reducing vibrations emanating from a machine, plant, or other vibration-emitting equipment is vital for
disturbance-free operation of the machine or plant itself, as well as for its surroundings. Conversely, it is
important to reduce external vibrations influencing the machine. Therefore, a distinction is made between
active isolation, which protects the surroundings from vibrations emitted by a machine (vibration emission),
and passive isolation, in which the machine or plant itself is protected from external interference (vibration immission).

Mounting a machine or plant on a vibration-isolated bedding reduces amplitudes resulting from sinusoidal
or shock excitation to a permissible operational level. Damping plays an important role in this, as it transforms
mechanical energy into heat and thus limits the amplitudes to a permissible level. It is important to choose a
suitable vibration isolator in order to achieve the best possible isolation effect.

In general, four different types of isolators are employed at different and sometimes overlapping frequencies.
– Air spring isolator: approx. 0.6 – 3 Hz
– Steel spring isolator: approx. 1.8 – 6 Hz
– Elastomer spring isolator: approx. 8 – 12 Hz
– Rubber mat isolator: approx. 15 – 35 Hz
