Abstract: A tuned mass damper (TMD) is disclosed. The TMD includes a mass and at least one spring coupled with the mass. The at least one spring having a spring rate. The TMD also includes a damper to dampen a motion of the mass, the damper having a damping coefficient. At least one of the spring rate and the damping coefficient are adjustable during a vehicle's operation to modify a frequency damped by the TMD.
