摘要
提出了一种新型断带抓捕液压系统,该系统主要由蓄能器、二通插装阀、液压缸、电磁换向阀组成,利用AMESim建立了系统仿真模型,给出了二通插装阀通径为32 mm、蓄能器阀充气压力为7 MPa、气囊容积为3 L等关键参数下的液压缸活塞位移曲线,分析了不同蓄能器充气压力、蓄能器气囊初始容积及二通插装阀通径对液压缸活塞位移的影响。结果表明:在初始元件结构参数下,液压缸活塞响应的时间为0.13 s;蓄能器充气压力增大会减缓液压缸活塞响应,蓄能器气囊初始容积增大、二通插装阀通径增大会加快液压缸活塞响应。
A new hydraulic system of broken belt capture equipment is proposed. It mainly consists of a hydraulic cylinder, an accumulator, a two-way cartridge valve, and magnetic exchange valves. The models of system are modeled by AMESIM. The diplacement respnse curve of cylinder poiston is given when the diameter of two-way car- tridge valve is 32 mm, the charge pressur of accumulator is 7 MPa, and the volume of the bladder is 3 L. The diplacement respnse of cylinder poiston is anayzed with different charge pressures of accumulator, volumes of the bladder, diameters of two-way cartridge valve. The results show the response time of cylinder is 0.13 s under the initial parameters of components, the response of cylinder poiston decreases when the charege pressure of accumula- tor increases; the response time of cylinder poiston increases when the volume of accumulator bladder decreases or the diameter of two-way cartridge valve increases.
