Simulation of Different Vibration Modes of a Drum in Continuous Compaction Control Systems of Soil by Vibratory Rollers

Abstract

AbstractModern vibratory rollers are equipped with systems of continuous compaction control to quickly monitor the quality of soil compaction by vibratory rollers not only at individual points of sampling, but over the whole compaction area. The operation of the continuous compaction control systems of vibratory rollers is based on the calculation of CMV, RMV, CCV, and other indicators. The paper presents the results of a computational experiment on the comparative performance of CMV, RMV, and CCV compared to the newly proposed compaction value. As a result of computational experiment on the three-mass rheological model, it was found that this CV, with a reasonable choice of influencing factors, has a high sensitivity to changing the properties of soil during compaction by vibratory drum in partial uplift mode and indicates the transition of vibrations in the undesirable double jump mode. At the same time, CV is insensitive to changes in soil properties in constant contact mode, as are CMV, RMV, and CCV. Further studies should clarify the values of factors influencing the calculated CV for various types of soil compacted by different vibratory rollers, conduct field experiments, as well as improve the simulation of interaction between vibratory roller and the compacted soil.KeywordsSoilCompactionVibrationVibratory rollerCompaction criterionContinuous compaction control
