Determine the load that each mount will bear when supporting the equipment weight. Total weight divided by the number of
mounting positions is the load for each mount. This is only true
when having even weight distribution. Otherwise, distribute
weight accordingly.
2. Determine the lowest forcing frequency of the vibration source to be supported by the mounts. This is usually equal to the oper ating speed in revolutions per minute.
3. Choose the percent isolation that will be satisfactory for the
purpose. Except for special cases, 81% isolation is generally
considered satisfactory.

Mounts with curves below the point of intersection can be used as, at the given load, the deflection will be greater than the minimum required.
Note, however, that if the applied load is above
the line x--x on a curve, the mount is not recommended for this static load.

Mounts with curves above this point of intersection cannot be used, as the load (Step 1) is not
sufficient to produce the required minimum deflection (Step 4).

Referring to the load deflection graphs of the styles

Having selected the mount series, refer to the in

is to carry.
constraints on allowable deflection, attachment requirements,
etc. However, in the absence of any overriding consideration,
usually the mount that is selected has its curve closest to the
point of intersection (Step 6c); i.e., the mount with
the minimum deflection at the applied load.

Vibration Frequency vs Static Deflection vs Isolation Efficiency

Referring to the Basic Vibration Chart below, find
the static deflection for the forcing frequency (Step 2,
above) at the chosen percent isolation (Step 3).
Note that a mount must give at least this minimum static
deflection, with the specific load applied,to provide
the desired isolation.
