Modal Shakers
Force outputs from 18 lbf (80 N) to 475 lbf (2.1 kN)

Modal Shakers Are Used to Excite a Structure Via the Central Spigot with a Connecting Rod (Stinger), So That Energy Can Be Input Without the Mass or Dynamics of the Shaker Affecting the Response of the Structure

Modal Shaker Range
Data Physics GW M-Series modal shakers use linear bearings, in place of the more common suspension systems, to produce virtually zero axial stiffness and virtually zero mechanical damping. When combined with Data Physics’ linear amplifiers, operating in current mode, the resultant system force output will exhibit typically less than 1% electrical damping and the phase shift between drive current and force output will be typically less than 1°.

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. |
