SEISMIC VIBRATOR Russian patent published in 2013 - IPC G01V1/155 

FIELD: physics.

SUBSTANCE: disclosed is a seismic vibrator having a radiating platform connected to a vehicle by elastic members, mechanical force generators and a ballasting inertial mass. The mechanical force generators of the seismic vibrator are each made in form of at least two electrical coils connected in anti-parallel and stacked on each other in the horizontal plane in the middle part of an R-wave mechanical force generator, made from two dielectric rectangular plates which can move relative each other and have teeth and grooves in their outermost parts. At least one pair of vertical electrical coils, also connected in anti-parallel and generating S-waves, are placed in the grooves. The teeth of the upper and lower dielectric rectangular plates can move relative each other and are rigidly connected by the upper dielectric rectangular plate to the ballasting inertial mass, and by the lower dielectric rectangular plate to the radiating platform.

EFFECT: improved connection of the radiating platform with the ground for generating S-waves and, as a result, improved functional capabilities of the disclosed pulsed seismic vibrator.
