Abstract : A description is presented of the David Taylor Model Basin 5000-Pound, Three-Mass Vibration Generator designed to excite vibrations in large structures. Forces of up to 5000 lb in any direction perpendicular to the axis of rotation and moments of up to 8500 ft-lb can be generated over the frequency range from 0.42 to 33.3 cps. Forces and moments are varied by adjusting the eccentricity and speed of three rotating masses. The mechanical and electrical parts of the system and detailed operational instructions are described. An operation and maintenance check list is also included. (Author)
