…vibration test system that provides higher force and displacement capability in an air cooled package. Extending the force and displacement of the SignalForce air cooled shakers allows engineers to perform environmental shock and vibration tests without requiring water cooling. The new air cooled shaker is capable of 13,500 lbf (60 kN) for sine and random. The shaker, whose operating frequency ranges up to 3 kHz, can produce a maximum displacement of 3.0 inch (76.2 mm) peak-to-peak and a maximum continuous operating velocity of 79 ips (2.0 m/s).
Newer standards emerging from the aerospace, military, and automotive industries require this extended displacement for high level shock and harsh, low frequency random tests. Enabling users to perform these tests on air cooled shakers results in a cost savings compared to using water cooled shakers. The shaker comes equipped with a cast and hand-wound armature, opto-pneumatic load support and dual bearing axial guidance. Dual bearing guidance is a unique feature that helps to reduce the amount of dynamic cross axis and rotational motion in the shaker armature during test. Additionally, the armature for the LE-1316-3 shaker is cast, not welded or assembled, for superior durability.
