Vibration Analysis & Control


Vibration is a mechanical phenomenon whereby oscillations occur about an equilibrium point. The oscillations may be periodic or random but most often, vibration is undesirable. To mitigate the impact of vibration, we can either decrease the intensity of the vibration source or decrease the sensitivity of the equipment. Vibration sources and equipment sensitivity can be characterized using measurements from seismometers, accelerometers, or interferometers. We analyze the measurements to determine what structural improvement, vibration damping and/or isolation strategy can be implemented to mitigate the impact of vibration. Environment vibration measurements, careful design, and predictive modeling using modal analysis or harmonic response can be used to evaluate performance.
