摘　　要：以飞机压力加油总管出口燃油滤为研究对象,建立了油滤模型,比较了有无油滤对泵源压力脉动的影响,由于油滤本身具有容腔效应,只要油滤位置选择得当,对压力脉动的抑制有非常重要的意义。理论分析表明:当油滤位置正好处在压力脉动波幅处,吸收压力脉动效果好,滤波精度越高,抑制脉动后峰值越小,研究结果为实际系统油滤位置的确定提供了理论依据。The mathematical model of the oil filter in the pressure refueling main pipeline was established, the effect of pipeline with oil filter on pressure fluctuation was compared with the pipeline without oil filter, the suitable position of oil filter can take positive effect on restraining pressure fluctuation. The results of theoretical analysis indicate that the oil filter can restrain the pressure pulsation when oil filter is located in the pressure pulsating wave amplitude. The conclusions can used in determining the optimized position of oil filter in the pipeline network.
