Simulation of soil-compaction with vibratory rollers
Most frequently, vibratory rollers are used for compaction tasks during earth works and road construction. An increase in roller performance can be achieved by automatically adapting the machine's parameters which determine the compaction result and by automatically controlling the state of compaction continuously. The actual problem is, that because of the extensive variety in properties of the materials to be compacted and the conditions in job site, it is very difficult to state the criteria for the feedback control of the roller parameters. By means of modelling and simulating, the vibration behaviour and compaction effect as well as the interdependence between the state of roller-operation and the state of soil-compaction is investigated. The goal is to aquire knowledge about the interactions between vibratory rollers and soil during compaction in order to improve roller construction and automatic compaction measuring-systems.
