1、CivilAviationUniversityofChina中国民航大学本科生毕业设计(论文)民航客机典型机型门的差异和排故案例分析Differencestypicalairlinerdoormodelsandtroubleshootingcasestudies摘要改革开放以来,我国民用航空的发展取得了举世瞩目的成就。航空运输保持了快速增长,航空网络不断拓展,机队规模不断扩大,民航业迅猛发展,2013年中国民航运输旅客人次近3亿,居世界第二。随着航班的增加,飞机维修业务也是逐年递增,通常在飞机维修遇到的故障中,门发生的故障率是很高的,特别是登机门、勤务门、货舱门等。飞机
2、门使用率高出故障率也高,而且门对于飞机来说是一个非常重要的部位:加上飞机门机构复杂,维修时很头疼。所以对于各种民航机典型门的差异性进行研究是十分有必要。如:手柄机构的差异性、开关门的差异性、门的收放位置的差异性、门的支撑部件的差异性、门的支撑部件的差异性、止动件的差异性、门的密封条的差异性、门的应急机构的差异性,以及典型机型排故的案例分析。使在维修时提高对于各型门的理解和辨别认知,结合平时工作中维修门时遇到的一些问题做经验总结。关键词:门的原理;门的差异;门的故障-iii-ABSTRACTSincethereformandopeningup,thedevelopment
