Dynamic Load Analysis of Forging Manipulator during the Whole Forging Stroke

Forging manipulators have to withstand powerful short-period impact loads. When designing a forging manipulator, the bending moments transmitted to the manipulator through the workpiece due to the press motions should be reduced to avoid the damage of the manipulator and the workpiece. A resilient system is often designed to achieve this purpose. The objectives of this paper are to discuss the dynamic behavior of the manipulator in the forging process, which focuses on the bending moment transmitted to the manipulator. The forging operation parameters are important for design, such as the press velocity profile, the press down duration and the decompression duration. A parametric study is conducted to provide practical guidance for the design of the forging manipulator.
