滨州学院本科毕业设计（论文）Aircraft Landing Gear Distributed Control Systemand Reliability AnalysisAbstractDuring take-off and landing of an aircraft,the landing gear controlsystem will directly affect its safety.The centralized control system has lowreliability and high wiring complexity.At the same time,it is nottime-sensitive in application and cannot meet the actual applicationrequirements in the development process of the control system.Under thebackground,the distributed control system was formally born.Based on theTTCAN communication protocol,the targeted design of the aircraft landinggear distributed control system was carried out,and the specific performanceof the TTCAN network was analyzed and discussed.The electrical controlpart of the landing gear retractable system is designed in a targeted manner.During the system design process,the bus-type and star-type hybrid Tuobastructure is applied.The overall system wiring is relatively simple,and at thesame time,it has better scalability.The system's fault handling capabilitiesand fault detection capabilities have been significantly improved.At thesame time,the redundant design of the system control unit,sensor,bus andactuator is removed,and the reliability of the system is comprehensivelyimproved.The landing gear distributed control system designed on the basisof the TTCAN communication protocol significantly reduces the wiringweight and wiring complexity,and comprehensively improves the real-timeperformance and reliability of the system.It meets the needs of the systemand can further improve the aircraft's landing gear.The economy,safety,etc.of the control system of the retractable and retractable landing gear havecertain practical significance.
