摘要
对轴向柱塞泵流量脉动进行了分析研究,通过对流量方程进行傅立叶变换,求得流量方程的另一种表达式,即泵的流量可以分成常量部分以及脉动部分,同时对脉动部分的各次谐波幅值进行了研究和讨论,得出了在系统中加阻尼后,能起到阻容滤波的作用,在一定程度上减小了压力脉动的幅值。
Based on the analysis of the axial piston pump＇ s pulsant flux, through fourier transform, another flow equation is obtained, the pump flow can be divided into constant part and pulsating part. Research and discussion of the pulsating part of the various harmonic amplitude, are conducted the conclusion is that by adding a damper in the system, the pressure pulsation of the amplitude can be reduced to a cetain extent.
