Principles of Operation of a Mechanical Reaction Shaker
2 x eccentric masses x eccentricity Hence, the amplitude of vibration may be varied simply by changing the eccentric mass or the eccentricity of this mass. Note that a mechanical shaker maintains a constant displacement over its frequency range for any given setting of the eccentric weights and test mass.
