Co-simulation Research Of Floating Cup Axial Piston Pump Based On ADAMS And AMEsim

Hydraulic transmission is widely used in national defense, metallurgy,aerospace sector. In modern hydraulic transmission, the axial piston pump is one ofthe most widely used hydraulics components. Heavy-duty hydraulic machines,vehicles and military weapons widely use the axial piston pump.Traditional swash plate and bent axis piston pump structure research has beenMatured, but the noise, leaks, wear and improve work efficiency problems are stillneed to be further improved. The beginning of the21st century, the NetherlandsInnas proposed a new floating cup structure. They did a theoretical research of itswork performance and made the first physical prototype test in2005.The resultsshow that the floating cup structure has some advantages compared to thetraditional structure in improving of flow pulsation, increase of work efficiency, noisereduction and so on.In this paper, the theoretical analysis of structure and work characteristics offloating cup axial piston pump are made. Dynamics model and hydraulic systemmodel of the floating cup pump are built in ADAMS and AMESim. With the interfacemodule between the ADAMS and AMESim, we build a co-simulation platform of thefloating cup pump.Through the co-simulation platform, we do some simulationresearches about cup motion characteristics, torque transmission characteristics,spherical hermetically sealed construction and transposition construction of the portplate.From analysis of the co-simulation result and the theoretical analysis, we getthe change law of working parameters, sum up the merits of floating cup structurecompared to traditional structure and prove the advantage of the sphericalhermetically sealed construction and transposition construction of the port plate. This build a good foundation for the further study of the new floating cup pump.
