Vibration Isolation System for a Large Industrial Process Equipment

DEICON designed and fabricated the components for vibration isolation of a massive 110,000 lb, industrial process equipment, subject to random perturbation. The isolators used in the random vibration isolation system are made up of low-stiffness coil springs paired with viscous dampers. Motion control schemes were incorporated into the isolation system to manage the lateral excursion of the equipment. Comparison of the measured vibration at various points on the equipment and their corresponding points on the support structure, point to the effectiveness of the isolation scheme.
