Abstract：

The travel positioning accuracy and start-stop stability of forging manipulator are always important parameters in large forging equipment. Therefore, by building the simulation model of walking dynamics and hydraulic system for 5 t forging manipulator, using the AMESim-ADAMS co-simulation method, the influences of main hydraulic components of manipulator walking system on the travel positioning accuracy and start-stop stability were studied by more accurate load. The co-simulation results show that hydraulic pipeline, travel relief valve, pump head relief valve and proportional directional valve all have certain influences on the travel positioning accuracy and start-stop stability of forging manipulator. In order to improve the travel positioning accuracy and start-stop stability, the influence of each component in the hydraulic system should be considered comprehensively, and the hydraulic components should be matched reasonably. Thus, it can provide a theoretical basis for the subsequent development, design and optimization of the walking system for forging manipulator.
