In this paper a multibody dynamic model of a wheeled tractor-front-end loader system with pneumatic boom suspension is created. A front-end loader was designed and manufactured to validate the dynamic model and to conduct proving ground tests. Comparisons of some simulation results with the measured data revealed that the proposed dynamics model can well describe the vibrations of the tested compact wheel loader. In addition, the results of tests for RMS acceleration and spectral densities at different speeds are presented.
