Abstract
Method and apparatus for providing an indication of compaction in vibration compacting machines. A signal proportional to acceleration occuring when the working part of a vibrating compaction machine strikes soil is developed by means of an acceleration pick-up and is compared with a stepped sequence of potentials representative of preselected acceleration values. During consecutive observation intervals it is observed which of these potentials are exceeded and which are not exceeded by the maximum acceleration occuring in an observation interval. In one embodiment, a control signal is developed which provides an indication of the compaction. The control signal is used to change the preselected acceleration values dependent upon the degree of compaction. Another embodiment of the invention develops a signal which is used to change the distance between the preselected acceleration values independent of the control signal.
