Finite Element Analysis to Vibratory Drum - Soil Model of Vibratory Roller

Abstract

In this paper a dynamical equation about vibratory drum - soil system was set based on the non-linear character of vibration compaction of vibratory roller. The finite element model of vibratory drum - soil system was established by the finite element software ABAQUS, with which the vibration compaction process of vibratory drum is simulated. According to the analysis of the vibration propagation on the soil surface, the longitudinal vibration propagation of soil, the stress and strain of the soil under the vibratory drum, results have proved that it is valid to simulate the interaction between vibratory drum and soil by the nonlinear finite element method, which offered a new way to research the interaction between vibratory drum and soil.

An advanced ICMV for vibratory roller compaction

“…In more recent research, dynamic elasto-plastic finite element models have been developed (e.g., [4,5,19]) to investigate the interaction between a vibrating drum and the soil. Kenneally et al [11] already highlight the importance of the consideration of the variable contact geometry between the drum and soil in their FE analysis.…”
