| Despite new technological solutions and attempts to improve the working conditions during driving of vehicles, city bus drivers are still exposed to negative impacts of noise and vibrations, causing stress, increased fatigue and leads to numerous diseases. Therefore it seems merited to investigate the acoustic climate and the working conditions during the operation of Solaris Urbino 18 vehicles, widely used in public transport systems. The main purpose of this research program was to show the impacts that the conditions at work might have on bus drivers or to demonstrate that these impacts do not exist. No extensive major research was done to investigate the influence of the conditions at work on functional stability of bus drivers. Investigation of vehicle vibroacoustic climate in working (normal) environment are led rarely. Measurements often are done in idle run or during ride at manoeuvring site only for 2-3 min. In this paper results of acceleration and noise in idle run are presented for 3 min measurement and for 3 h until ride. All measurements are done in working environment on streets of Tychy city with passengers on board. In this paper detailed numerical analysis of vibroacoustic parameters are presented. Physical parameters like noise spectral analysis in 1/3 octave frequency bands and histogram of acoustic pressure level in the driver's cabin are presented in results. |
