  • Basics of Vibration Measurement

    Vibration is measured either in terms of displacement, velocity or acceleration. Vibration displacement is always measured as Peak to Peak, a measure of the total excursion of the rotor or machine casing in MILS or MICROMETERS. Vibration velocity and Acceleration are measured as Zero to Peak or RMS. Units used are "inches per second" or ...

  • Vibration Absorbers: Types, Working, Specification, …

    How Does a Vibration Absorber Work? The basic principle behind a vibration absorber is the phenomenon of resonance. Resonance occurs when the frequency of the vibration is equal to the natural frequency of the mass-spring system. At resonance, the amplitude of the vibration can be very high, which can cause damage to the mechanical system.
