Abstract

This paper deals with the dynamic modelling of a vibratory asphalt compactor. A compactor is a machine of road building site. Its task is to increase the density of the asphalt. The aim of the study is to estimate contact efforts between the drums of the compactor and the bituminous mix. These drums vibrate. Robotic formalism is used to model the compactor as an articulated mechanical system. Thus, the dynamic model is computed automatically. This model is modified in order to adapt it to our system of measurement. In this way, it is sufficient to model drums to estimate contact efforts. The model is linear according to a set of dynamic parameters which can be identified using a Weighted Least Squares method. The identification is carried out through dedicated experiments. During these experiments, contact efforts were known. Thus, parameters are identified. During a real worksite, it has been possible for the first time to estimate contact efforts applied by a compactor.
