Resumo:
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.
