Abstract
The theory of the damped dynamic vibration absorber, neglecting the effect of damping in the main mass system, has been worked out and is available in the literature. However, a search of the literature reveals a lack of experimental verification of the theory. This is probably due to the general unavailability of suitable experimental apparatus such as the Westinghouse vibration fatigue testing equipment recently acquired by the United States Naval Postgraduate School, and which is one of the first commercial units of this type to be built. During the period from October 1948 through April 1949 the author extended the theory of the damped dynamic vibration absorber to include the effect of damping in the main mass system, designed a suitable absorber unit for application to an elastic system driven by the above noted fatigue testing equipment, and ran tests to obtain experimental verification of the theory. This work was carried on at the United States Naval Postgraduate School.
