Relations entre l'exposition des conducteurs aux vibrations multidirectionnelles, le confort et le siège utilisé

Abstract

It has been demonstrated that driving some heavy vehicles in the mining, forestry and construction industries leads to whole-body vibration exposure exceeding the prescribed limits. The researchers will measure, in the field, the multidirectional characteristics of the vibration transmitted in different vehicles including scoop trams in mines, scrapers on construction sites, and skidders in forests. Reproduced in the laboratory on a multi-axial vibration simulator, the vibration will be statistically related to the degree of discomfort felt by the participants sitting on seats installed on the simulator. Two types of suspension seats and one rigid seat will be considered in the tests. A better understanding of the effect of the vibrations acting in several directions simultaneously and the behaviour of the seats under such conditions will better identify the actions to be taken to improve driver comfort and to limit their exposure to vibration, which may contribute to the development of low back pain and injury.
This project is funded by the Workplace Safety and Insurance Board (WSIB) of Ontario and involves collaboration between the IRSST and Guelph and Laurentian Universities and the University of Western Ontario, as well as the Construction Safety Association of Ontario.
