2025E Modal Shaker

The 2025E Modal Shaker is a very lightweight electrodynamic modal exciter, capable of providing up to 13 lbf (58 N) of peak force excitation, a 0.7 in (18 mm) general purpose stroke and a useful frequency range beyond 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, or chirp excitation signals. The through-hole armature design with chuck and collet attachment is ideal for use with either traditional modal stinger rods or piano wire stingers, which help to decouple cross-axis force inputs, minimizing input force measurement errors while using the modal shaker.
