In the present investigation a contribution is offered in order to improve the knowledge of the influence of both speed and tyre type on a medium power tractor vibrations. The vibrations transmitted from the ground to the driver’s seat of a ballasted wheeled tractor of medium power, equipped with a front suspension axle and a suspended cab, have been measured and analyzed. Two different tyres, namely, types A and B, at two different forward speeds, 11.1 and 13.9 m s-1, have been experimentally tested, during the simulation of the front agricultural implements transportation on a rectilinear plane tract of a conglomerate bituminous closed track. This work has been done by applying standards recommended by ISO 2631/1, 1997. Results were obtained on the... |
