The Modal Shop, a PCB Group Company, introduces the 2100E11, a new, light-weight modal shaker. The unit is capable of providing 100 lbf (440 N) of peak force excitation in a small footprint weighing less than 33 pounds. With a 1” stroke and frequency range up to 3000 Hz, the 2100E11 is suitable for most structural testing modal analysis applications, including single and multiple inputs (SIMO and MIMO) using random, burst random, sine dwell or chirp excitation signals. While an optional air cooling package is offered for high force range operation, most modal applications use the shaker in uncooled operation.
The 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 Modal Shop’s 2150G12 1/16” diameter stingers, or piano wire stingers, like The Modal Shop’s K2160 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 shaker.
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.
As with all equipment from The Modal Shop, the modal shaker is backed by PCB Group’s Total Customer Satisfaction guarantee.
