This paper presents dynamic analysis of a hydraulic excavator based on experimental data. A three dimensional multibody model of a hydraulic excavator is modeled for the computer simulation. The hydraulic pressures acting on the cylinders are measured from experiments, and the forces exerting on the cylinders are calculated from the measured pressures. Using these forces, the dynamic analysis of the excavator is carried out to regenerate the motion in the computer simulation. A proper operation scheme is assumed to match the computational result and the experiment. The DADS program is used for the dynamic analysis.
