Traditional Seismic Mitigation Methods
Traditional mitigation strategies for securing electronics cabinets and other equipment have run the gamut from the failed “do-nothing” or just “let-it-roll” philosophy, to bolting, cross-bracing, and structural stiffening of cabinet frames. While these methods may work to keep the equipment or cabinet frame upright, they actually increase the likelihood of system failure as they provide a direct pathway on which damaging shock and vibrations can travel. The more rigid the connection, the more likely there will be damage to drive heads, optical lasers, and other sensitive componentry.

The Innovative Seismic Mitigation Solution

Illustrates the use of a dual-platform base isolation system. The bottom platform moves with ground motion, thereby minimizing the transfer of shock and vibration into the frame. The bearing acts as a “white-noise” filter isolating the top platform from damaging vibrations. This allows equipment to continue to operate right on through seismic activity.
