Characterisation of vibration exposure in industrial, utility, mining, and public transport vehicles Abstract Over the past few years, many inquiries have been made in Québec concerning the choice of suspension seats adapted to the vibratory context of city buses, snow tractors and lift trucks. In the absence of data on the characteristics of the vibrations to be attenuated in these vehicles, few technical tools were available to help make informed choices regarding vehicle seats or modifications to reduce drivers’ vibratory exposure levels. This study first defined the spectral classes of vertical, longitudinal and lateral vibrations as well as the typical pitch and roll vibrations in four vehicle categories (city buses, snow tractors, and sit-on and stand-on lift trucks). A mathematical model of a snow tractor was also created to evaluate the desired effect of certain design modifications to this type of vehicle on vibratory characteristics.
