Forging manipulator is very important auxiliaries in forging hydraulic press unit, the development direction of forging manipulator is fully hydraulic of forging manipulator with fast response speed large output power and high precision, which is a complex equipment with mechanical systems, hydraulic systems, control systems became one. The two actions system has the working characteristics such as large inertia, load changes and control of high precision, so to develop co-simulation research on machinery system and hydraulic control system has have theoretical and practical significance in engineering.It is difficult to meet the requirement of fast accelerating and precise positioning for domestic forging manipulator with relatively low hydraulic system. In this paper, based on the 20T forging manipulator, the virtual prototype of 20T manipulator was built by using body simulation software ADAMS, combined with parametric modeling software Pro/E and system simulation software AMESim, The main studies are as follows:(1)The main component of system and hydraulic station was calculated and chosen by theoretical calculation based on the hydraulic system principle of 20T forging manipulator. The mathematical modeling of tong rotation and cart walking was found.(2)3 D solid model was built by using Pro/E. The dynamics model of tong rotation and cart walking was built by using Mechanical / Pro interface program introduced solid model into ADAMS. The electro-hydraulic proportional valve of static and dynamic characteristics was studied by using AMESim software, compared with the experimental data, to get reasonable parameters. The simulation model of accumulator and hydraulic station was built and studied the characteristics of pump outlet accumulator, laid the foundation for co-simulation. (3)The collaborative simulation model of tong rotation and cart walking was built and simulated using ADAMS/CONTROL control module and AMESim Interface. The response curve of rotation and axial feeding was analyzed under fast and constant forging model by real-time data exchange. The influencing factors for system was analyzed under different load and different accumulator parameters.
