Evaluation of the Vibratory Effect Transmitted by Road Buses Bodyworks

The objective of this work is to evaluate the levels and vibratory effects that the passengers who use intermunicipal road buses are submitted. In the study, measurements of the accelerations produced in the vertical direction had been carried through according with norm ISO 2631, in two bus bodyworks, of different manufacturers, in a normal situation of use, in three points of it (frontal, central and back). With the measurements it was possible to point which are the places in the bodywork interior and the points in the seats that produce greater accelerations r.m.s. The results had been evaluated and compared with the curves values established for norm ISO 2631 in relation to health and comfort and in relation to fatigue, comparing the two tested bodyworks.
