When designing forging manipulators, the bending moments transmitted to the manipulator through the workpiece due to the press motions should be reduced to avoid damage to the manipulator and the workpiece. A resilient system is designed to this purpose. This paper investigates the dynamic behavior of the forging manipulator due to press motions, which focuses on the bending moment transmitted to the manipulator. The Forging manipulator parameters assume primary importance in design, such as the clamp mass, resilient stiffness, resilient damping. A parametric study is committed to provide some helpful solutions for forging manipulator design.
