摘要
以某型号电液比例负载敏感多路阀为研究对象,构建其电液比例系统的AMESim仿真模型。通过设置主阀阀芯处的间隙与偏心值,得到考虑泄漏时颤振输入信号幅值与频率和内部主阀前阻尼孔直径对主阀阀芯位移和输出流量的影响。结果表明:随信号频率的增大和幅值的降低,两参数波动幅值逐渐降低;阻尼孔直径在影响超调量、响应时间的同时,也影响两参数波动幅值。仿真分析结果可为实际应用中颤振信号的确定提供参考。
Taking a certain type of electro-hydraulic proportional load-sensitive multi-way valve as the research object,the AMESim simulation model of its electro-hydraulic proportional system was constructed.By setting the gap and eccentricity at the main valve spool,the influence of the amplitude and frequency of the external flutter input signal and the diameter of the front orifice of the internal main valve on the fluctuation of the main valve spool displacement and output flow were obtained when the leakage was considered.The results show that as the signal frequency increases and the amplitude decreases,the fluctuation amplitude of the two parameters gradually decreases;the diameter of the orifice affects the overshoot and the response time,but also affects the fluctuation amplitude of the parameters.The simulation analysis results can provide reference for the determination of flutter signals in practical applications.
