SEISMIC SOURCE Russian patent published in 2008 - IPC G01V1/02 

FIELD: physics.

SUBSTANCE: invention is related to vibration and pulse seismic engineering. Seismic source contains vehicle, radiating plate, ballasting mass, electromagnet exciter of vibrations with power coil, system of its energising and control. At that in seismic source the following elements are introduced: elastic elements, coil of excitation of electromagnet exciter of vibrations, hoisting and clamping mechanism, elastic isolation with vehicle, bridge power commutator of power coil. Radiating plate, which is connected with anchor of electromagnet exciter of vibrations, is equipped with elastic element placed on this radiating plate, on which stator of electromagnet exciter of vibrations is directly placed with two coils. Between stator and anchor the second elastic element is placed, and stator with arranged stands on both sides, which are stems of hydraulic cylinders, is connected with pistons of these hydraulic cylinders, casings of which in top and bottom cavities are equipped with nozzles and via springs and shock absorbers are connected to vehicle, which is equipped with specified ballasting mass, which is rigidly fixed to this vehicle.

EFFECT: provision of possibility of creation of pulse and vibration forces, regulation by amplitude of created forces and frequencies of vibrations, reduction of mass in transport condition.
