Abstract
In one embodiment of the present invention, a drive assembly for a seismic land vibrator is provided. The drive assembly comprises at least a first spring element. The first spring element operates in at least two vibration modes in a seismic frequency band of interest. The drive assembly also comprises a baseplate, a driver, and a reaction mass. The driver interacts with the reaction mass and the first spring element to transfer energy to the baseplate.
