摘要
通过对轴向柱塞泵泵壳体振动加速度信号的理论分析及实验研究 ,得出轴向柱塞泵转轴基频的四次谐波能量及其转轴基倒频率的二次谐波能量是诊断单个柱塞松靴故障的敏感参量。
The case's vibration accelerate signals of axial piston pump were analysed on the theory and researched on the experiment.It presented that the four harmonic energy of the rotary axis base frequency and the two harmonic energy of the rotary axis base inverted frequency of the axial piston pump are sensitive parameters for diagnosing single piston loose slipper fault.
