Abstract
This disclosure describes a system and method to calculate a ground stiffness value. The system includes at least one sensor configured to sense at least one of a vertical acceleration, vertical displacement, and a force of a compactor component and a processor configured to calculate a force at a drum-ground interface in response to the at least one sensor and further configured to calculate a drum displacement in response to the at least one sensor. The processor is further configured to determine ground stiffness using the calculated force at the drum-ground interface and the drum displacement.
