Shaker Model 2025E

Modal Exciter 13 lbf

Model 2025E

When performing experimental modal analysis, the choice of excitation function and system can make the difference between a good measurement and a poor one.  For many modal test applications, an electrodynamic shaker system is best suited for creating an appropriate input forcing function.  Distributing adequate input force energy across the test structure and obtaining accurate and reliable input force measurements is critical for successful modal testing.  This often requires a shaker that is highly portable, rugged and easy to set up in order to facilitate the best exciter location (relative to the test structure) while minimizing any unwanted interaction between the exciter and test structure.

The Modal Shop 2025E, a very lightweight electrodynamic modal exciter, is capable of providing 13 lbf (58 N) of peak force excitation in a small footprint weighing just 13 lb (6 kg).  With a 0.7 in (18 mm) stroke and frequency range up to 9 kHz, the 2025E is suitable for structural testing and experimental modal analysis applications, including single and multiple inputs (SIMO and MIMO) using random, burst random, sine dwell and chirp excitation signals.
