Abstract
The dynamic equilibrium equation of the swash-plate axial piston pump was established based on its geometric, kinematic and hydraulic parameters. The dynamic equilibrium equation was solved, and from the three load transmission paths between the pump rotor and the housing, the dynamic loads of the slippers, bearings, valve-plate and other moving parts on the housing were determined one by one. The dynamic load of the moving parts on the housing was used to replace the interaction between them, so as to realize the unidirectional decoupling of the housing structure and moving parts. The finite element model of the piston pump housing was established, and the model was verified by experimental modal analysis. The dynamic loads were applied to the housing structure under different working conditions, then the dynamic response of the housing structure was calculated, and verified by the measured data. Then the vibration magnitude of housing structure based on vibration intensity was evaluated. Dynamic characteristic analysis of housing for swash-plate axial piston pump laid a foundation for its housing structural optimization design for vibration and noise reduction.
