摘　　要：针对传统气囊式蓄能器在放能过程中出现的压力波动问题,提出一种双气囊式蓄能系统以保证出口压力的恒定。利用比例换向阀、传感器设计一种具有比例反馈环节的新型双气囊式蓄能系统,阐述新型双气囊式蓄能系统的基本结构与工作原理。利用AMESim软件建立新型双气囊式蓄能系统的仿真模型,将其应用于具体的液压系统油路,再与单一蓄能器的作用效果进行对比。结果表明:在相同的工作压力下,对新型双气囊式蓄能系统进行了有效的压力补偿,保持了系统所需压力的稳定供给。With respect to the pressure fluctuation of traditional gasbag accumulator in the process of discharging energy,a double gasbag energy storage system is proposed to ensure the constant outlet pressure.A new type of dual air-bag energy storage system with proportional feedback link is designed with proportional reversing valve and sensor,and the basic structure and working principle of the new dual air-bag energy storage system are described.The simulation model of the new double-balloon energy storage system is established by AMESim software,applied to the specific hydraulic system oil circuit,and compared with the effect of a single accumulator.The comparison and analysis results show that the new double-airbag energy storage system,under the same working pressure,can effectively compensate the pressure and maintain the stable supply of pressure required by the system.
