Vibration Motor Principle

Tuned mass damper Wikipedia

The graph shows the effect of a tuned mass damper on a simple spring mass damper system excited by vibrations with an amplitude of one unit of force applied to the main mass m important measure of performance is the ratio of the force on the motor mounts to the force vibrating the motor F 0 / F assumes that the system is linear so if the force on the motor were to double
