摘　　要：针对当前预制桥墩浇筑过程中模具的对接、调平、内部清洗以及脱模等工作难以通过人力完成的问题,设计一套圆柱桥墩浇筑模具工作液压系统。通过分析模具工作要求,采用多路阀控制整个液压系统,实现不同执行元件的复合运动要求。建立AMESim仿真模型并进行分析,得到液压缸在不同C v值下的动态特性曲线,并根据仿真结果对液压系统进行实验验证。结果表明:额定压力设定为16 MPa时,该液压系统能满足实际工作的负载要求,还能提供足够压力保证液压缸的速度和行程要求;系统C v值设定为0.3~0.7时,满足系统变速要求且速度波动小;仿真结果与实验结果基本相符,验证了液压系统的有效性。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 composite motion requirements of different actuators were realized.The AMESim simulation model was established and analyzed,and the dynamic characteristic curves of the hydraulic cylinder under different C v values were obtained,and the hydraulic system was experimentally 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 hydraulic cylinder.When the system C v 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.
