Inertial Shakers
Force outputs from 7 lbf (30 N) to 56 lbf (250 N)
When Large Structures Need to Be Tested, Inertial Shakers Provide the Ideal Solution
| These shakers have found applications for testing buildings, floor loading resonances, ship’s decks for helicopter loading, squeaks and rattle testing in cars, geological exploration, helicopter rotor simulation and active vibration cancellation. The central spigot is attached to the structure under test and the body then provides the inertial mass. |
Inertial Shaker Range
Inertial shakers are permanent magnet devices which may be sealed for short test operations in harsh environments. For prolonged use it is necessary to cool the shakers and this can be achieved either by the attachment of a standard shop dry air line or by the attachment of a small cooling blower to suck the air through the shaker.All power amplifiers used with inertial shakers may be fitted with an internal sine signal source to provide simple excitation for the shaker. Externally generated signals may also be applied to the power amplifier.

How to Choose the Right Vibration Shaker for Testing
The first step in selecting the correct shaker is to define the test profiles that are to be run (sine, random, shock, replication, etc.) and to gather dimensional information on the test article and fixtures that will need to be used (LxWxH and total mass).
For any shaker, the added mass of the device under test (DUT) and fixtures moves the performance envelope from the black line to wherever the red line might be. Shaker sizing calculations are done to make sure all test profiles will fit within the envelope.
| This graph is a generic (frequency domain) performance envelope for any shaker, as defined by its maximum displacement, maximum velocity, and maximum force. |
