INFLUENCE OF THE ROAD TYPE ON THE WHOLE BODY VIBRATIONS TRANSMITTED TO THE DRIVER OF AN ELECTRIC TRACTOR

Whole body vibration (WBV) is a potential condition leading to occupational diseases in tractor operators. A method of evaluating the vehicle's vibration reduction properties. One way to analyze the properties of the tractor in order of reducing the vibrations felt by the operator while driving, to improve comfort and safety, is to use electric tractors. The literature has confirmed that the emission levels of the WBV electric tractor depend very much on the nature of the operation per-formed, the speed parameter and the nature of the road. This study high-lights the influence of the combination of the speed (speed v1 = 5 km / h) of the electric tractor (model TE-0) and the roughness of the road surfaces (straight road, uneven road, rough road and plowed land). The acquisition of data during the experimental tests was done with the Biometrics software, and the processing and interpretation of the values of the accelerations produced, with the dedicated software Vats Nex Gen Ergonomics.
