Modal Shaker 13 lbf

Experimental Modal Testing Exciter | Model 2025E

The Modal Shop’s Modal Shaker Model 2025E, a very lightweight electrodynamic modal exciter, is capable of providing up to 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) general purpose stroke and 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.

Highlights

  • Through-hole armature with chuck and collet attachment provides simple set-up with modal stingers
  • Lightweight and portable – weighing just 13 lb (6 kg) with an approximately 5 in (125 mm) square footprint
  • Trunnion base provides flexibility and easy set-up when aligning the shaker and choosing best exciter location(s)
  • 0.7 in stroke and broad frequency range supply adequate input energy for most small to mid-sized modal test applications
  • Ambient air cooling sufficient to meet full shaker performance (13 lbf/58N) specifications

The 2025E modal exciter is supplied in a trunnion base allowing full rotation for easy set-up. The through-hole armature design with chuck and collet attachment is ideal for use with either traditional modal stinger rods or piano wire stingers. These stingers greatly simplify test set-up with an easy connection to the force sensor and test structure, and help decouple cross-axis force inputs, minimizing input force measurement errors while using the modal shaker.

All of The Modal Shop modal shakers are supplied in a trunnion base allowing full rotation for easy set-up. The through-hole armature design with chuck and collet attachment is ideal for use with either traditional modal stinger rods, like the 2150G12 (1/16 in diameter stingers) or piano wire, like the K2160G piano wire stinger kit with force sensor quick disconnect. These stingers greatly simplify test set-up with easy connection to the force sensor and test structure, and help decouple cross-axis force inputs, minimizing or eliminating input force measurement errors. For horizontal force inputs, the modal shakers adapt directly to the 2050A lateral excitation shaker stand, allowing convenient position adjustment over a wide area relative to a test structure.
