Abstract: The kinematics and dynamics of operating device for electro-hydraulic overhead loader are analyzed and the mathematical model is established. Then, computer simulation is carried out for the operating device. Based on the results of simulation, a all round discuss is made for the relation between the construction parameters and its effect on the motion of the operating device. Finally, some problems which should be considered in practical design and the solving methods are presented.
