報告摘要：

With the increasing demand of the civil aircraft, the shortening of the flight cycle renders the increase in aircraft take-off and landing year by year, as a result, the performance of the landing gear is put to great tests. The frequent failure of the landing gear retraction system has severely influenced the safety of the aircraft; consequently, carrying out detailed reliability research on the landing gear retraction system is of great significance to guide the design and to improve the reliability performance of the landing gear retraction system. The landing gear retraction system of an aircraft, including mechanical and hydraulic systems, is complex and nonlinear. It has many uncertain factors, including the crosswind velocity, the diameter of the damping orifice, liquid capacity, friction, and oil leak, which lead to difficulty in dynamics and reliability analysis. In this presentation, a 3D main landing gear of a certain airliner is treated as the object of study, and research is conducted on the landing gear retraction system performance analysis, as well as its reliability.
