VORRICHTUNG ZUR BODENVERDICHTUNG UND ÜBERWACHUNGSVERFAHREN
A device for ground compaction, comprising a frame and a drive motor supported by the frame, a vibration exciter driven by the drive motor and a ground compaction apparatus, in particular a base plate or a roller drum, that is connected to the vibration exciter, wherein the vibration exciter causes the ground compaction apparatus to vibrate at a fixed vibration frequency or within a vibration frequency range during a compaction operation, and wherein a conversion device for the conversion of vibrations into electric energy is provided which converts vibrations of the device for ground compaction into electric energy, wherein the conversion device comprises two spring-mass systems with different resonance frequencies, and wherein a control unit is provided which determines the degree of compaction of the ground from the electric energy obtained by the individual spring-mass systems, in particular the respective voltages. Moreover, the invention relates to a method for monitoring changes in the ground compaction produced with a device for ground compaction.
