某型发动机二速传动机构故障分析(论文15000字)
摘要
按照传统时间表的维护系统是耗钱、耗力的，并且只能给出不全面的对二速传动机构故障的检测和诊断。现代飞机发动机的监控和诊断系统具有让维护人员获得关于探测和诊断二速传动机构故障的有价值信息的能力。讨论现代航空发动机监控系统和故障诊断系统的组成，功能，以及相关的监控和分析参数。讨论的航空发动机滑油分析系统的原理与构成。最后，通过CFM56-3C滑油碎屑分析作为实例，阐述了二速传动机构滑油分析的具体步骤和结论，为二速传动机构的监控趋势分析提供了理论依据。
本文以相关技术资料为依据,通过实际工作的探索与机会,结合故障排除经验,以某型发动机为主要对象,较全面系统地阐述了该型二速传动机构起动系统的工作原理,并对影响启动的外界因素加以说明和分析。希望能够帮助大家进一步熟悉和了解二速传动机构起动系统概况。

Fault Analysis of Two-speed Transmission Mechanism of a Certain Type of Engine
ABSTRACT
According to the traditional schedule of maintenance system is cost, power consumption, and can only give a comprehensive two-speed transmission mechanism fault detection and diagnosis.Modern aircraft engine monitoring and diagnosis systems enable maintenance personnel to obtain valuable information about the detection and diagnosis of two-speed transmission mechanism faults.This paper discusses the composition and function of modern aeroengine monitoring system and fault diagnosis system, as well as relevant monitoring and analysis parameters.The principle and constitution of the lubricating oil analysis system for aeroengine are discussed.Finally, the concrete steps and conclusions of the oil analysis of two-speed transmission mechanism are expounded through the example of cfm56-3c oil debris analysis, which provides a theoretical basis for the monitoring trend analysis of two-speed transmission mechanism.
