The magnitude of the vibration is equal to the magnitude of the force times the mobility of the structure. From this it follows that the amplitude of the destructive forces acting on a machine are not determined directly by measuring its vibration if the mobility of the machine is not known.

Aug 10, 2016018332A time-varying applied force causes the mass to oscillate back and forth. Now if we also have a set of initial conditions umathbfx,t0u0, then we can compute the displacement response of this system over time. The plot below shows the displacement of the mass with the applied load, ftsinomega t, and initial condition, u00. Under.
See DetailsElectromagnetic actuators play an important role in vibration control, 1,2 where the largest output force of the conventional electromagnetic actuator is restricted to a very narrow bandwidth around the natural frequency. With the purpose of solving this problem, there has been much recent interest in the design of natural frequency adjustable devices whose natural frequency can be adjusted by.
