Simulation and Optimization Analysis of Swash Plate Axial Piston Pump

The stable operation of hydraulic systems in marine engineering ascent and descent compensation equipment is crucial for deep-sea operations. The inherent periodic pressure pulsation problem of the swash plate axial piston pump, as a commonly used power source, affects the stability and power consumption of the system. In this study, based on the principle of piston motion, the steady-state characteristics and flow pulsation of the swash plate axial piston pump were analyzed using AMESim simulation software. Through the combined use of AMESim and particle swarm optimization algorithms, an optimization analysis of the swash plate inclination, oil fluid modulus, and pump outlet pressure was achieved, successfully reducing the flow pulsation rate of the piston pump and improving the stability of the hydraulic system. This optimization method not only simplifies the mathematical modeling process but also provides feasibility for the optimization analysis of practical operating conditions, making it of certain engineering reference significance.
