PULSED GROUND-BASED NON-EXPLOSIVE SEISMIC VIBRATOR

摘要

FIELD: physics.SUBSTANCE: seismic vibrator has an antenna board, a tightening weight supported by the antenna board and a pulse motor which generates force between the board and the tightening weight. The seismic vibrator also has a damper whose rod is supported by the tightening weight. Between the chassis of the damper and the board there is an elastic member which reduces repeated shocks on the board generated by the tightening weight and dynamic loads on the damper. The elastic element can be in form of a compression spring.EFFECT: high efficiency operation of the seismic vibrator.3 dwg
