Abstract
An assembly for providing an active seismic source includes a motor and a drive shaft coupled to the motor. A crank is coupled to the drive shaft. The motor is configured to impart rotation of the crank in a first rotational direction. A one-way bearing permits rotation of the crank relative to the drive shaft in the first rotational direction and inhibits rotation of the crank relative to the drive shaft in an opposed second rotational direction. The assembly also includes a strike plate, a track, and a hammer that is movable along the track along an axis that extends toward and away from the strike plate. The hammer contacts the strike plate. A biasing element biases the hammer toward the strike plate. A linkage arm couples the hammer to the crank and translates rotational movement of the crank to linear movement of the hammer.
