In this paper, the fault analysis of an aircraft nose landing gear’s emergency lowering was conducted with a cosimulation method. The simulation was aimed at studying the dynamic response characteristics of landing-gear retraction/extension. Moreover, the equations of the mechanical and hydraulic system were derived and analyzed so as to acquire th...
The landing gear retraction system of an aircraft, including mechanical and hydraulic systems, is complex and nonlinear. It hasmanyuncertain factors, which lead to difficulty in reliability analysis.To makethe reliability analysis more accurate and efficient, some studies are represented in this paper. Taking the main landing gear of an aircraft as...

... As elucidated in [1][2][3][4][5], in modern civil aircraft, the landing gear system is the primary takeoff and landing device, and the landing gear's performance is critical for flight safety. Hydraulic retraction/extension (R/E) of the landing gear is one of the most crucial subsystems on the landing gear, and if it fails during the landing phase, it can easily to cause a serious accident in which the landing gear cannot launch, posing a serious threat to takeoff and landing safety. ...

... Bai et al. 9 proposed a MDCRSA method based on the response surface methodology and Monte Carlo to study the reliability analysis of the gear transmission errors of the steering mechanism of the gun (GTESMG). Yin et al. 10 set up the reliability limit state equation of the retraction system by busing a quadratic polynomial that has no cross terms and discussed how the key parameters affect the reliability of the retraction system. Zhang et al. 11 derived a quadratic polynomial function by using the response surface method to describe the quantitative relationship between the tooth modification parameters and the dynamic transmission error fluctuations of helical planetary gear pair. ...
