Modal Shaker Modal Shop 2100E11

Automotive and Aerospace Exciter | Model 2100E11

The Modal Shop 2100E11, 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 in stroke for solid low-frequency performance and useful high-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.

Highlights

• Through-hole armature with chuck and collet attachment provides simple set-up with modal stingers
• Lightweight and portable – weighing just 33 lb (15 kg)
• Trunnion base provides flexibility when choosing best exciter location(s)

• 1 in 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 / 440N) specifications

The 2100E11 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, helping decouple cross-axis force inputs and minimizing input force measurement errors while using the modal shaker. For horizontal force inputs, the 2100E11 adapts directly to The Modal Shop’s 2050A lateral excitation shaker stand.
