Parametric Design And Simulation Research Of Axial Piston Pump

As an important component of the hydraulic system, axial piston pump is widely used inengineering machinery, ship industry, vehicle industry and so on, depends on it’s higherrevolving speed, working pressure, volume efficiency and lower production cost. In recent years,the demand of pump’s displacement, working pressure and revolving speed becomes higher withthe development of mechanical industry. Along with the pump’s series production level isimproved continuously, the piston pump’s update rate is accelerating ceaselessly.Due to the high similarity degree of the axial piston pump’s parts, the work of productdesign is mainly about the size’s modification which is based on the same structure. Therepetitive work wastes a lot of labor resources and design time, which can not meet the need ofmodern production’s development.This paper takes a theoretical analysis for the axial piston pump, and works out theparameter’s bound relation during the part’s design. According to the parametric design,develops axial piston pump’s parametric design system with Pro/Toolkit’s secondarydevelopment, to realize the parts’ automatic modeling.The software’s detection and mechanism simulation found that the system is stable andfeasible, and its functions correspond with the design requirement. Apply the static analysis,modal analysis and harmonic analysis in the structural strength and vibration conditions of thepart’s model with the finite element analysis method. The use of the system shortens the axialpiston pump’s design cycle greatly, and improves the design efficiency, it also providestheoretical basis for the further research of axial piston pump.
