Structural Dynamics of Process Equipment Structure Case Study

Problem

A major petrochemical facility was experiencing vibration problems with a shaker structure. The shakers used in the process service caused destructive vibration levels of the building containing the equipment. KHE was contracted to identify and resolve the problem.

Solution

KHE developed a finite element model of the structure using ANSYS. We were able to match the actual response numerically and thus determined the root cause of the problem. There was inadequate isolation between the shakers and the structure. KHE de-tuned the structure using the computer simulation by choosing appropriate vibration isolators that were implemented in the new design.

Results

The new design eliminated the problem.
