SELECTION METHOD
Please select the model matching the load and desired
performance.
1. If the machine has the normal frequency, obtain the
exciting (forcing) frequency.
2. Calculate the load of one mount.
3. On the load vs natural frequency chart, go horizontally
from the load calculated in step 2 till it intersects the lines
representing different mounts.
4. From the intersection, go vertically down to get the natural
frequency.
5. Select the model that suits the machine (choosing between
emphasis on safety or vibration damping). Generally, if the
exciting frequency is more than twice the natural frequency, there is effective attenuation of vibration. Conversely,
if the exciting frequency is below 2 times the natural frequency, you are close to the resonance frequency. Select
an alternate model in this case.
NATURAL FREQUENCY (Hz)

1. Use the natural frequency figure only when the forcing
frequency is in the vertical direction.
2. To emphasize safety, reduce the load on each unit. To
emphasize vibration damping, operate in the maximum
load area.
3. To emphasize vibration damping, match the models to
each support load so that the natural frequencies are
uniform as much as possible.
