In order to predict the dynamic behaviors of the wheel loader during the traveling on the road with the bump, the analytical model of the wheel loader was built up and the vehicle dynamic analysis was carried out using ADAMS program. And the dynamic behaviors of the traveling wheel loader were measured to verify the validity of the vehicle dynamic analysis procedure. The acceleration peaks of the cabin were found in both analysis and measurement results when the wheel loader was passing over the bump and the calculated dynamic behaviors showed good agreement with the measured ones. Therefore it was concluded that the vehicle dynamic analysis procedure established in this paper was valid.

This paper presents the inverse dynamic analysis of the wheel loader manipulator based on the experimental data. A three dimensional rigid multi-body model of the wheel loader manipulator was built up. The inverse dynamic analysis for the typical operation mode was carried out by the ADAMS program. In order to verify the analysis result with the measured one, the hydraulic pressure and displacements of the cylinders were measured and the inverse dynamic analysis was carried out using experimental data. From the results of the analysis and measurement, it was concluded that the computational driving force showed good agreement with the measured one.
