ESTUDO SOBRE O CONFORTO VIBRACIONAL EM DIFERENTES VEÍCULOS E PAVIMENTAÇÕES: UMA REVISÃO SISTEMÁTICA

ABSTRACT The vehicles use has been growing since the industrial revolution and, along with it, the concern about the driver comfort and passengers. It is known that vibrational comfort is decisive, especially to ensure the driver’s health. In front of the occupational risk involving vibrations, the present study aims to make a systematic review about the vibrational comfort in different vehicles, delimiting the results to articles from the last 10 years that used the ISO-263:1997 and 5349-1: :2001 standards for evaluation. Wholebody vibrations (WBV) and hand-arm system vibrations (HAV) in different vehicles were studied, as well as the influence of the pavement on vibrational comfort. It was observed that the vibration of stationary cars and motorcycles was considered comfortable, and, as expected, lower when compared to the vibration from displacement. As for trucks, a vibration between 0.747 m/s2 and 0.804 m/s2 (seat) was observed and converges between the literature. Furthermore, studies affirm that truck’s drivers should not work more than 8 hours a day. Regarding the axes, the z axis was predominantly observed. For motorcycles, vibrations were rated as uncomfortable. There is unanimity regarding the pavement: the lower vibration is proportional to the better quality of the road. Keywords: Health. Standards.
