Abstract

Vibrations of agricultural tractors and other off-road vehicles are mainly excited through uneven ground encountered by such vehicles. Thereby tire acts as geometrical filter that transforms short-wavelength road undulations into effective excitation profile of milder geometry. Being geometrically conditioned, this filtering behaviour depends on tyre radial deflection i.e. contacts length. In this paper examination of sensitivity of filtering behaviour to contact length change is described and results are presented.
