Zusammenfassung:FIELD: vibration engineering. ^ SUBSTANCE: method comprises generating loading pulses of different polarity whose duration is less than the half of the vibration-seismic vibration half-period and affecting the emitting plate with the pulses. The duration of the pulses should provide the decrease of vibration velocity of the emitting plate of the vibration-seismic source down to zero when next loading pulse of opposite sign comes for one- or bi-polar modulation of the loading pulse. ^ EFFECT: enhanced power coefficient. ^ 3 dwg
