VIBRATION SOURCE OF SEISMIC SIGNALS Russian patent published in 2003 - IPC

FIELD: seismic prospecting, evaluation of seismic stability, and other engineering investigations. SUBSTANCE: device designed to excite seismic vibrations in natural (earth's interior) and man-made (buildings, structures) entities for nonexplosive investigations of these entities is secured through bottom rod of hydraulic cylinder directly on supporting slab between side member and cardan shaft asymmetrically relative to longitudinal vertical plane crossing gravity center of vehicle. Supporting slab is made asymmetric so as to maintain equally distributed symmetrical transmission. EFFECT: enhanced seismic efficiency. 1 cl, 3 dwg
