The Swedish Road and Traffic Research Institute has on behalf of the Transport Research Commission of the Royal Swedish Academy of Engineering Sciences carried out measurements of the dynamic rear wheel load on uneven roads of two buses with different suspension systems. The aim was to validate a mathematical vehicle model developed by Volvo. The dynamic wheel load is determined as the sum of the static wheel load and the product of the wheel spring rate and the standard deviation of the axle height when driving on uneven road sections.
