Abstract:

The compacting effect which a vibrating compactor has on the ground is greatly affected by its mechanical factors such as weight, frequency and dynamic force. In this paper, we study the relationship among the mechanical factors of a vibrating compactor, the ground conditions and the compacting effect of a compactor on the ground through a numerical simulation. The simulation made it clear that there exists an optimum frequency at which the compactor can generate its maximum compacting effect for the ground and that the optimum frequency is proportional to the ratio of the ground stiffness to the weight of the compactor. Based on the results of the simulation, we suggest a method to determine the optimum frequency for the ground. We also discuss the possibility of developing an automatic adjustment system by which the ground conditions can be evaluated; using the vibrating behavior of the compactor, and the vibrating conditions can then be adjusted according to the evaluated ground conditions.
