As the power sources in hydraulic systems, variable displacement axial piston pumps generate flow fluctuation. Unfortunately, it results in pressure pulsation which excites the system vibration and emitted noise. The majority of studies try to elimin

Publikováno v: Zhang, J, Xu, H, Chen, J, Huang, W, Huang, X, Lv, F, Xu, B, Pan, M & Su, Q 2022, ' Modeling and Analysis of the tilt behavior of the cylinder block in a high-speed axial piston pump ', Mechanism and Machine Theory, vol. 170, 104735 . https://doi.org/10.1016/j.mechmachtheory.2022.104735

Increasing the rotating speed of the axial piston pump is effective in improving the power-to-weight ratio. However, the cylinder block tilts severely at high speed, which causes significant leakage. In this paper, a dynamic model of the rotating ass

Publikováno v: Measurement. 167:108279

The cylinder block is the main rotating part in axial piston pump, and its dynamic characteristics can reflect the health condition of the pump more directly than the external characteristics. In this paper, a less modification measurement scheme is
