APPARATUS AND METHOD FOR GENERATING A SEISMIC SIGNAL |
摘要 |
<p>A seismic signal generating system comprises a hammer positionable to impact a baseplate assembly. An actuator acts cooperatively with the hammer to urge the hammer to impact the baseplate assembly. A friction brake is actuated to impart a friction force to the striker. The friction force restrains motion of the hammer until the brake is released. A method of generating a seismic signal comprises coupling a hammer to an actuator. The hammer is restrained from motion using a friction brake. The friction brake is released such that the actuator urges the hammer into contact with a baseplate assembly generating a seismic signal.</p> |
