BUFFERING APPARATUS FOR LANDING GEAR BUFFERING STRUT

摘要

A buffering apparatus for a landing gear buffering strut and a method for using same in an air-oil buffering strut. The buffering strut (200) comprises an outer cylinder (201) and an inner cylinder (205) able to move along the inside wall of the outer cylinder (201); the buffering apparatus comprises: at least one excitation component, arranged on the inner side of the wall of the outer cylinder (201) of the buffering strut (200); at least one induction component, arranged in the inner cylinder (205) of the buffering strut (200) to respond to the excitation of the excitation component, such that the inner cylinder (205) moves along the inside wall of the outer cylinder (201) of the buffering strut (200) and produces buffer damping; a control unit, used for controlling the excitation component in real time on the basis of a motion signal of the buffering strut (200); and a sensing component, arranged on the lower end of the buffering strut (200) to detect the motion signal of the buffering strut (200) and to feed the motion signal back to the control unit. The semi-active control method of the present buffering apparatus is beneficial for adaptation to more complex external conditions, improves the buffering efficiency of an aircraft on landing, and, by using an excellent control algorithm, further enhances the safety and comfort of the aircraft landing process.
