摘要: 仿真分析是对复杂的起落架和液压系统进行性能分析的主要方法。针对起落架液压收放系统的健康管理问题,在分析系统工作原理和故障特性的基础上,以AMESim软件作为仿真平台,建立起落架液压收放系统的结构模型,仿真了系统的工作过程,获取多个部件不同健康状态的性能参数数据,为后续故障诊断、健康状态监测与评估奠定了基础。

关键词: 起落架液压收放系统, 仿真, AMESim软件, 健康管理

Abstract: The simulation is a normal way to analyze system performance of aircraft landing gear and hydraulic system. Health management of aircraft systems is now a research focus. In this paper, principle and fault characteristics of landing gear hydraulic retraction/extension system were first studied. Simulation model based on AMESim software was established and the factors affecting on the working performance of the system was analyzed. Various outputs of several components vs different health situations were obtained, which lay the foundation for further fault diagnosis and health management.

Key words: landing gear hydraulic retraction/extension system, simulation, AMESim, health management
