Abstract：The composition and control technology of the 3 000 kN/7 500 kN·m ultra large hydraulic forging operating machine were introduced.A parallel motion decoupling hanging mechanism was proposed,which has sufficient load-bearing capacity to ensure the reliable clamping and smooth operation of the forging during operation.A multi-mode collaborative control strategy with six degrees of freedom,including displacement,rotation,and swing,was designed to meet the high-precision positioning requirements of the large forging operating machines under small step and high-frequency working conditions.The strategy achieved smooth,impact free,and accurate position control under ultra large moving inertia.
