The larger the amplitude, the more movement or stress is experienced by the machine, and the more prone the machine is to damage. Vibration amplitude is thus an indication of the severity of vibration. In general, the severity or amplitude of vibration relates to: (a) the size of the vibratory movement (b) the speed of the movement
