基于AMESim的某型运输机地面扰流板内漏故障研究

摘要

液压系统内漏是航空维护比较麻烦的问题,影响因素多,排故复杂,所需时间比较长.利用AMESim软件对某型运输机地面扰流板内漏进行故障仿真,分析出该型运输机地面扰流板常见的故障类型大都与液压相关;利用AMESim软件进行液压仿真建模,分析扰流板作动筒在不同内漏间隙、不同负载和不同液压压力下的内漏情况.文中研究可为机务维护人员在维护飞机时提供参考.%The internal leakage of the hydraulic system is very trouble in aviation maintenance.The influence factors are many.The troubleshooting process is very complex.The time required is very long.AMESim was used to set up the internal leakage model for a certain type of transport airplane's ground spoiler.The conclusion was that the common failure type of the aircraft ground spoiler was about the hydraulic system.The hydraulic simulation model was built based on AMESim.The internal leakage in cases of the actuator with different internal leakage gap,different loads,and different hydraulic pressure were analyzed.This research can provide reference for aircraft maintence person when he is in maintenance.
