To solve the problem of justifying the characteristics of vibrating rollers, choosing a roller model for working under specific conditions, setting up the technological modes of compaction in a vibrating roller, it is required to model the dynamic interaction of a vibratory drum with the compacted soil. The mathematical model should allow us to study both the continuous and alternating contact operation modes of the vibratory drum and be consistent with the experimental results. The paper presents the results of the computational experiment based on a triple-mass rheological model of interaction between a vibrating roller and soil. It shows that the proposed model adequately reproduces vertical displacement and acceleration, as well as spectra of the vertical accelerations of a vibratory drum in a DM-614 roller during soil compaction. The conducted computational experiment of justifying the value of the apparent mass of soil showed that the best results can be achieved with value of the apparent mass of soil equal to 20% of the mass of the vibratory drum, which corresponds to the results of other researchers.
