Air-Cooled Electrodynamic Shaker System

Data Physics Corporation has announced the release of the SignalForce model LE-1316-3/DSA10-100K electrodynamic shaker system, a shock and vibration test system “that provides higher force and displacement capability in an air-cooled package,” allowing engineers to perform environmental shock and vibration tests without the need for water cooling.

According to the company, new aerospace, military, and automotive industry standards require extended displacement for “high level shock and harsh, low frequency random tests.” Featuring an operating frequency up to 3 kHz, the new air-cooled shaker from Data Physics Corp. “is capable of 13,500 lbf (60 kN) for sine and random,” and “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).” In addition, the new shaker “comes equipped with a cast and hand-wound armature, opto-pneumatic load support and dual bearing axial guidance.”

“The 1316 shaker at 60 kN makes the SignalForce line more competitive and provides more capability than the competition,” Kevin McIntosh, director of product management for the SignalForce and SignalSound product lines, said. “Along with the increase in available force and displacement, proprietary flexures combined with dual bearings provide superior cross axis and rotational stiffness.”
