Abstract
An apparatus for use in an active suspension system includes a mass damper for damping a first vertical resonance of a wheel having vertical and horizontal diameters. The wheel defines a wheel plane that passes through a center of the wheel and the wheel's vertical and horizontal diameters. The wheel also defines a transverse wheel plane that is perpendicular to the wheel plane and that intersects the wheel-plane along the vertical diameter. The mass damper includes a damping mass coupled to the wheel. The damping mass is constrained from motion relative to the wheel in all but a vertical direction and has a mass distribution that is asymmetric relative to the transverse wheel plane.
