The vibration amplitude can be modified by adjusting the unbalance weights (by increasing or decreasing mass of the unbalance weights). To generate vibration in a vibration system, one of the shafts of the unbalance exciter is driven by stationary drive motor through cardan/propeller shaft (a shaft fitted with universal joints at each end).
The vibration excited by the two-dimensional valve is influenced by pressure saturation, the elastic force, and the hydraulic resonance. There is a critical valve linear opening, beyond which the output force (torque) reaches a saturation value in both a positive and negative sense.
