The Ultimate Guide to Vibration Analysis

Nov 12, 2018· Vibration is an oscillating motion about equilibrium, so most vibration analysis looks to determine the rate of that oscillation, or the frequency that is proportional to the system's stiffness. The number of times a complete motion cycle occurs during a period of one second is the vibration's frequency and is measured in hertz (Hz).
