| The mechanism reliability widespreadproblems of militaryaircraft are common concern, andthereliabilityofsomemechanisms is criticalfor thesafety of aircraft. With the development of science and technology, thelandinggeardevelops towardamoresecure, higherreliability, andtherefore it is meaningful to conduct the research on the reliabilityanalysis of the landinggear.Relative lack of system reliability studies for military aircraft, targeted research, in this paper, this aspect of the research institutes of reliability. It discusses the main analytical approach for planar skeletal mechanismstructure, locomotion and force analysis. It also introduces the principle、methods and procedures of mechanism reliability analysis.The landing gear retracting-extending mechanism is one of the key components of a military aircraft, whose reliability or otherwise related to the safety of aircraft. Based on the theory of a certain type of military aircraft landing gear retraction mechanism has been simplified mathematical model of institutional reliability computing, applications and genetic algorithm toolbox of Matlab and Kriging model combined with the structure of the retractable institutions analysis and calculations, and comparison with several other traditional reliability calculation methods to obtain the corresponding reliability parameters, combined with the general factors that affect the reliability of the agency conducted a reliability analysis and calculation, to obtain the relevant conclusions. For aircraft landing gear at the very moment that the reliability of emergency put the landing gear mechanism were analyzed to establish the reliability of the model, combined with the effects of different ambient conditions on the landing gear to work, the application of Matlab software correlation analysis, resulting Conclusion avoid air accidents that have some significance. |
