航空柱塞泵系统建模与仿真研究

摘要

航空柱塞泵作为飞机液压系统的心脏，其工作性能将直接关系到飞机控制系统的安全性与可靠性。根据某航空泵的结构与工作原理，以AMESim软件为仿真平台，建立了航空柱塞泵主要元件仿真模型，并进一步搭建了整泵系统仿真模型。仿真过程中柱塞泵的斜盘预置夹角以及斜盘转轴偏心参数的引入，使得系统仿真更符合实际情况。通过仿真研究为后续泵的参数优化提供了理论指导，并建立了航空液压柱塞泵系统仿真的原准机模型。%Air Piston Pump, as the power source of main hydraulic system for aircraft, its performance directly relates to the safety and reli-ability of the flight control system. According to the structure and working principle of a certain type of air pump, the simulation models of main components of Air Piston Pump are developed, based on the AMESim simulation software platform, which further builds a simulation model for the entire pump system. The inputs of swash plate pre-tilt angle and hinge eccentricity make Air Piston Pump system simulation more realistic. Through studies of such simulation, the theoretical guidance is provided for the follow-up pump parameters optimization and the standard simulation model for Air Piston Pump system is set up.
