Section 5.4.1: Earthquake Vibration

Earthquake simulation using prescribed acceleration time history waveform. The severity of the test is determined by the geographical location of the equipment installation.

Recommended Test Equipment

UD Model SAI60-LS12-X Seismic Test System
Vwin Vibration Control System w/ Seismic Control Test Software
Different mounting platform sizes available. Consult factory.

Unholtz-Dickie introduces a new vibration test system that performs the diverse requirements of the Bellcore (GR-63-CORE) test specification for telecommunications equipment. This new system combines the high frequency, low noise benefits of an electrodynamic shaker with long stroke capability.

Until now, multiple test systems were required to run all the tests requirements of the Bellcore specification. Typically, a standard electrodynamic shaker would be used to run the Office and Transportation Vibration profiles, while a long stroke hydraulic actuator would be used to run the Seismic Waveform.

Major advances in long stroke electrodynamic shaker design allow all tests to be run on one test system, resulting in lower capital equipment costs, as well as increased performance and test accuracy.
