Análise das vibrações e identificação paramétrica em tratores de pneus agrícola.

Abstract

In this work has been presented a study on the leveis of vibrations that the tratoristas, in general, is exposed in its work place. The use of rnodeling techniques, seeking the establishment of a group of equations that can monitor the previous analysis of the behavior dynamic vibratory and/or of the system tractor appropriately in its interaction with the soil, is a reality. In this work, is considered two aíternatives to monitor and to verify the leveis of vibrations that the tratorista is exposed. The first is to consider in the model of interaction soil-structure the three vibration manners that, one understands they be the most important. Soon after, it tries to verify the answer vectors in displacements in the domain of the frequency (vibrations of the structure of suspension of the tractor) starting from a procedure using technique of identification of parameters - inverse problem. It is verified that the resolution method used for the obtaining of the vector in displacement and the developed generic formulation and used for the process of identification of parameters in the domain of the frequency they are fully satisfactory.
