Abstract:

In order to study the problem of large fluctuation in the startup speed of heading press mobile workbench under different loads, for the 40 MN heading press, based on the theoretical analysis of force for the hydraulic cylinder in the mobile workbench during startup process and simulation software AMESim,the hydraulic circuit in the mobile workbench was modeled and simulated, and the change curves of pressure and velocity for the oil inlet end of hydraulic cylinder in the mobile workbench were obtained. Then, the corresponding change curves of pressure and speed were obtained by adjusting the load weight and whether to add the speed control valve, etc., and the comparative analysis was conducted. The simulation results show that the addition of speed control valve in the hydraulic circuit of the mobile workbench greatly reduces the fluctuation of startup speed and pressure in the mobile workbench under different loads.
