Differential equations of the rigid vibratory drum interaction with compacted soil

Abstract

Differential equations of the rigid vibratory drum dynamic interaction with compacted construction soil are obtained, and relationships of the vibratory drum geometric parameters with soil characteristics and technological parameters of the soil compaction process are determined. The vibration exciter driving radial force has been replaced by the vertical driving medium operating constant force. The vibratory drum interaction with the soil is considered during a vibration exciter eccentric weight half-turn during which the vibratory drum singe influence occurs on the compacted soil. The reaction force of the vibratory drum with the soil is written using the linear Hooke’s law, that has allowed to obtain an analytical solution adequate to the real process of the soil compaction by the vibratory drum.
