摘要：

针对锻造液压机系统中部分执行机构需要很高的工作压力，而其余大部分机构所需工作压力比较低的情况，提出了一种基于双向增压器的新型液压储能系统。泵组输出的油液经过增压系统增压后，油液压力得到显著提升，然后与传统液压动力单元一起为主工作缸供能。该系统克服了液压机加工过程中负载的时序性和周期性，因此，在液压系统设计过程中可以选择装机功率更低的电机-泵组单元，从而组成更为经济合理的液压系统。通过仿真结果可知，采用双向增压装置后系统的输出流量保持较高的稳定性与响应性，且与传统液压机相比，具有质量轻、体积小和结构紧凑的优点，应用前景十分广阔。

For the fact that some actuators in the forging hydraulic press system required high working pressure, while most of the other actuators required relatively low working pressure, a new hydraulic energy storage system based on a bidirectional supercharger was proposed. When the output oil of pump unct was pressurized by the supercharging system, the oil pressure

was significantly improved, and then together with the traditional hydraulic power unit, it supplied energy to the main working cylinder. The system overcomed the timing and periodicity of the load in the process of hydraulic press. Therefore, a motor-pump unit with lower installed power was selected in the hydraulic system design process to form a more economical and reasonable hydraulic system. The simulation results show that the output flow of the system keeps high stability and responsiveness after using the bidirectional supercharging device, and compared with the traditional hydraulic press, it has the advantages of light weight, small volume and compact structure, leading to broad application prospect.
