| Abstract: | Based on the widely used push bar tong of large scale heavy-load forge manipulators,establishes the mechanical model between the driving force and the tong force,which considers the effect of friction moment,inertia force and radius of the workpiece when the jaws are in the vertical and horizontal position.Dynamic simulations are performed by the dynamic simulation software ADAMS.The computational results of the mechanical model are in agreement with the simulation results of ADAMS,proving that the mechanic... |
