Dynamic simulation of the vibratory roller – terrain interaction using an elastoplastic approach

Résumé

This study deals with the problematic of deep interaction between the terrain and the vibratory drum at the technological process of dynamic compaction. In this paper is briefly presented a theoretical approach of this dynamic phenomenon based on a set of conservative and frictional dissipative rheological models. Simulation results reveal proper evolution of the numerical models comparative with the real systems behavior. Hereby, timed evolutions of both elastic and consolidation stages, in strength linkage with vibration parameters and terrain characteristics, enable the algorithmic developing of the interaction characteristics in terms of technological equipment and processed material.
