Abstract

See full text

A seismic vibrator is configured to operate close to resonance for range of actuating frequencies. The vibrator has a baseplate, a reaction mass coupled to the baseplate via an elastic coupling mechanism and an actuator configured to displace the reaction mass with an actuating frequency. The vibrator also has a frequency-adjusting system configured to adjust a natural frequency of the elastic coupling mechanism and the reaction mass, to track the actuating frequency so that to achieve resonance.
