| Abstract: | There are complex dynamic interactions between vibration wheel and soil in the process of vibrating compaction.In this paper,a finite element model of the vibration wheel and soil in ABAQUS was established;vibration compaction process was analyzed;the results demonstrated that finite element model could be a good simulation of the nonlinear response of the vibrating compaction process,which could help design and predict vibratory roller compaction effect. |
