On the Efficiency of Compacting Equipment

Abstract

In this paper, the efficiency of vibratory rammer during compaction is examined. A three-degree-of-freedom model has been established for analytical representation of the soil-rammer interaction. In the first approach, it was considered only the vertical rammer movement. The soil is characterised as linear model taking into account the influence of the next properties: elasticity, plasticity and viscosity. A programme in Matlab/Simulink 7 was developed to solve the system of differential equations, which describe the rammer movement. The simulation results are presented as diagrams of displacement and acceleration of the main parts of the system.
