The Modal Shop 2100E11 Modal Shaker, a lightweight electrodynamic modal exciter, is capable of providing 100 lbf (440 N) of peak force excitation in a small footprint weighing just 33 pounds (15 kg). With a 1” stroke and useful frequency range beyond 5400 Hz, the 2100E11 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. 

Benefits: 

• Through-hole armature with chuck and collet attachment provides simple setup with modal stingers.
• Lightweight and portable – weighing just 33 lbs (15 kg).
• Trunnion base provides flexibility when choosing best exciter location(s).
• 1” stroke and broad frequency range supply adequate input energy for most modal test applications.
• Forced air cooling sufficient to meet full shaker performance (100 lbf pk) specifications.
  
  

The 2100E11 Modal Shaker is supplied in a trunnion base allowing full rotation for easy setup. The through-hole armature design with chuck and collet attachment is ideal for use with either traditional modal stinger rods, like the TMS 2150G12 1/16” diameter stingers, or piano wire stingers, like the TMS K2160G Piano Wire Stinger Kit with force sensor quick disconnect. These stingers greatly simplify test setup with an easy connection to the force sensor and test structure, and help decouple cross-axis force inputs, minimizing or eliminating input force measurement errors while using the modal exciter. For horizontal force inputs, the 2100E11 adapts directly to The Modal Shop’s 2050A Lateral Excitation Shaker Stand. Using four turnbuckles, the modal shaker is supported by its trunnion base and can be adjusted over a wide horizontal and vertical area relative to the test structure.
