Pass-axis Axial Piston Hydraulic Motor Pump Flow Field Simulation And Motion Dynamics Analysis

In recent years, the country has been advocating the idea of efficiency, energy saving,environmental protection in various fields of production of life for people is also true forthe development direction of the hydraulic. The hydraulic pump as the hydraulic system ofthe power source has achieved rapid development in these years. The integration ofhydraulic pump and motor of the research has also made a lot of results, improvedutilization of energy, reducing environmental pollution. Therefore, the very broadapplication prospects of this new type of hydraulic components should be continuedin-depth study.The axial piston hydraulic motor pump researched in the article adopted structure ofthe integration of hydraulic pump and motor pump, the axial piston hydraulic pump’scylinder and the motor’s rotor are connected together by the special gear couplings, so thestructure is more compact, small size, reduce the loss of energy transfer, increasing energyefficiency, reducing noise and vibration problem. With the development of computertechnology and the rise of computer-aided engineering technology has played a large rolein the study of hydraulic components. In this article, the internal flow field characteristicsof the axial piston hydraulic motor pump is used in CFD technology, the movementdynamics of the pump makes use of virtual prototyping technology.(1)This article overviews the research development status of the motor pump, theCFD technology and virtual prototyping technology in the study of piston pump.(2)The axial piston hydraulic motor pump’s internal flow characteristics are carriedout the numerical simulation based on the CFD technology., can be obtained from thesimulation results of the detailed parameters of the internal flow field’s and velocitydistribution and pressure distribution of each key position location, and provide referencedata for subsequent internal improvement of the flow channel.(3)Respectively, to use of the AMEsim software and the ADAMS software toestablish the hydraulic model and dynamic model of the moving parts in the axial pistonhydraulic motor pump, through data exchange, linking the two model co-simulation. (4)Under different conditions of the axial piston hydraulic motor pump’s flowchanges, pressure changes and the plunger movement can be obtained from theco-simulation results, comparative analysis of these results provide reference data forfuture optimization of the pump.
