Abstract
A vibration generator has rotatable imbalance masses disposed on at least two shafts, in which means for adjusting the rotational position of the imbalance masses relative to one another are disposed. There is at least one sensor for determining the angular acceleration of the rotating imbalance masses. The sensors may also determine acceleration of the vibration generator. There is a module for determining the angular acceleration of the rotating imbalance masses on the basis of the measurement values determined by the sensors. A vibration pile driver for introducing elements to be pile-driven into the ground, and drawing them from the ground, as well as for compacting ground material, contains one of the aforementioned vibration generators.
