VIBRATION EXCITER Russian patent published in 2003 - IPC

Abstract RU 2199131 C1

FIELD: seismic prospecting, evaluation of seismic resistance and other engineering surveys. SUBSTANCE: vibration exciter incorporates hydraulic cylinder, reaction mass, cross- piece, bearing plate, shock absorbers, electrohydraulic amplifier-converter, body, sleeve, double rod plunger, bearings. Diameter of rod in space above rod is less than diameter of rod in space under rod. Product of difference of effective areas of plunger by working pressure in hydraulic cylinder is equal to weight of reaction mass. EFFECT: enhanced functional reliability and simplified design of vibration exciter. 1 dwg
