move) down, taking shock shock P tangu 5 with me before meeting it with the radiating plate 2.

At the moment immediately preceding the impact of the radiating plate 2 and the shock bar 6, the carriage will have a maximum cKopocTi), pointing down, and the flywheel maximum speed pointing up, At the moment of impact, the speed is quenched, and under the action of springs 18, the system returns to its original position ( see fig, 1),

At the moment of impact (Fig. 2), the center of gravity 19 is not stirred down to point 21, and the center of gravity 20 — upwards to point 22. The ratio of the displacements of the centers of gravity is determined by the ratio of the mass of the flywheel with the rods G) and the mass of the carriage 4, springs 7, 8, 18 and shock 1ptap1-and 5.

In order to exclude the impacts of the loads 17 and the shock bar against the body of the source 3, the rigidity of the spring 18 is selected so that the time of the weighted state of the moving elements is equal to the time of bringing them to their original position.

The application of the invention makes it possible to provide a source of seismic vibrations with high reliability due to the exclusion of shock overloads when the flywheel interacts with a shock bar.

In addition, the possibility of energy storage due to overcoming the centrifugal s.t (.y magnetic force (MO coupling and compression of the spring) significantly reduces the drive speed and the total mass of the source of seismic vibrations while providing: , -1ay.

Form u l i and l doom shadow

. The source of seismic vibrations, containing a rotational drive, from a first plate and a housing in which a shock rod and a flywheel are placed, characterized in that, for the purpose of a new reliability, the upper guide connecting the shock rod with a rotational force is fixed on the housing. a rotary drive, and a lower guide, onto which the flywheel is supported, consisting at least of two separate loads made of permanent magnets, each of which is fixed by means of a spring-loaded rod on the carriage possibility of rotation of the plane passing through the rod axis of the shock, which top and bottom spring-loaded on the carriage, it is associated with keyed guide and passed through an upper guide, a flywheel and a lower guide for longitudinal relative movement.

2. The source of oscillations according to claim 1, characterized in that the connection of the shock rod 1D1 with the upper guide is made in the form of friction engagement.
