MODELING AND ANALYSIS OF VIBRATORY ROLLER DYNAMICS CONSIDERING THE MOVEMENT OF ADDITIONAL SOIL LAYER DURING COMPACTION

Abstract

In the actual compaction process of the vibrating roller, there is always an additional
amount of soil moving up during the compaction process. This paper presents a dynamic
model of the vibrating roller during operation that takes into account this additional
amount of soil movement. The dynamic model takes into account the coefficient of
elasticity of the suspension system of the base frame, the compacted soil and the additional
displacement layer. Based on the dynamic model, the Lagrange equation of the second kind
is used to build a system of differential equations describing the motion of the mechanical
system. The results of the paper are the basis for evaluating the compaction efficiency of
the vibrating roller as well as evaluating the stability and vibration during operation, which
is the basis for designing and improving the suspension system on the vibrating roller.
