Design and Research of Hydraulic System for Cylindrical Pier Pouring Mold Based on AMESim
In view of the problem that it is difficult to complete the docking,leveling,internal cleaning and demoulding of the mold in the pouring process of the prefabricated pier by manpower,a set of cylindrical pier pouring mold hydraulic system was designed.By analyzing the working requirements of the mold,the multi-way valve was used to control the whole hydraulic system,and then the com-posite motion requirements of different actuators were realized.The AMESim simulation model was established and analyzed,and the dy-namic characteristic curves of the hydraulic cylinder under different Cv values were obtained,and the hydraulic system was experimen-tally verified according to the simulation results.The results show that when the rated pressure is set to 16 MPa,the hydraulic system can meet the load requirements of actual work,and can provide sufficient pressure to ensure the speed and stroke requirements of the hy-draulic cylinder.When the system Cv value is set in the range from 0.3 to 0.7,it meets the requirements of system speed change and the speed fluctuation is small.The simulation results are basically consistent with the experimental results,which verifies the effectiveness of the hydraulic system.
