Abstract

Six buses were considered placing them under the same reference conditions at three different speeds. The correlation between the speed values and the vertical frequency-weighted acceleration is clear. The vibrations on the backrest, on the pedals and on the steering wheel are not a problem. The seat dampens the vibrations in the case of two buses, while it amplifies them in the case of the other three. Considering the transmissibility of vibrations through the seat, the measurements in reference conditions are predictive of those in working conditions, allowing to easily propose interventions to reduce the risk.
