Abstract
Vibratory drum is a compactor used to density soil, asphalt or other materials. Application combined static and dynamic forces to increase the load-bearing capacity of the surface. The combination of a vibratory drum and soil represents a closed-loop system. During compaction the mode of drum motion is distinguished as contact and bounce operation, because the drum leaves the ground when the vibrations exceed a certain intensity. The mode of drum motion at a certain time depends on the compaction force, the force transmitted in the contact area between drum and soil. The amplitude and frequency of drum movements cover is a wide range of values. This will vary with the conditions of the material being densities. The dynamic behavior of vibratory drums is determined by the combination of the drum and the soil to be compacted the dynamic force applied varies with the types and conditions of the material being compacted. The progress in compaction and the compaction result have to be controlled by adjusting the compactor parameters, excitation frequency and force, drum speed. The compaction effect of vibratory drums is investigated. This paper presents the design of the model of the frame-vibratory drum-competed soil system. This model is the foundation for all calculations and simulations for investigating various influences on vibration behavior of the drum and the compaction progress of the compaction soil. There was the mathematical description of the interaction between drum and soil during compaction. By Matlab-Simulink numerically simulate the frame-drum-soil system. There was done the method to define amplitude and frequency at which the combination of the drum and soil exhibits the greatest amplitude during compact soil.
