ABSTRACT:
A flywheel is equipped with dynamic dampers in the form of fluid-containing chambers. The fluid in each chamber has a characteristic frequency of oscillation that is a constant multiple of the rotational speed of the flywheel. In preferred embodiments, the characteristic frequency corresponds approximately to the strongest vibrational component produced during the operation of an engine on which the flywheel is mounted. When the flywheel is rotated, the fluid in the chambers vibrates and absorbs vibrations imparted to the flywheel.
