COMPLEX CONTINUOUS-LUMPED MODEL FOR SIMULATION OF VIBRATORY COMPACTION PROCESS

Abstract

The main goal of this study consists by a complex lumped-continuous model of terrain compaction and related machine-terrain interaction approaches. In this paper, the author tries to use a new method to evaluate and analyze the interaction between the vibratory drum and the terrain. The analysis is rheological approached, with a predominantly dynamic behaviour, in order to reveal the compatibility of the working body performances with the characteristics of the terrain. The study has made in the conditions of complex rheological approaches of a direct influence area of vibration on compacted domain material. Based on classical elastic and dissipative models the author was build a multiple layer continuous-lumped system that is able to simulates the continuous phenomenon during each layer taking into account discrete linkages between adjacent layers.
