Study on the Dynamic Performance of Heavy-duty Forging Manipulator
نویسندگان
چکیده
Cooperating with heavy forging press, the heavy-duty forging manipulator is used for handling the workpiece during the free-forging process. Therefore, the size accuracy of the forgings is related to the dynamics performance of the forging manipulator. This paper aims to study the dynamic performance of DDS heavy-duty forging manipulator. The kinematics model is firstly built to predict the trajectories of the tong. Then, the dynamics models are derived by using rigid-body method and flexible-body method respectively. Finally, the simulation results indicate that partially flexible-body model is well predicted the trajectory of the tong. Key-Words: -Forging manipulator, Dynamics model, Partially Flexible-body method, Trajectory
