Abstract :
A special adaptive shock strut of landing gear with double-cavity and double damping is studied in the paper. Its mathematical model and virtual prototype, which is established based on the software ADAMS, are described. The paper has emphatically studied the sensitivities of its different configurations and main parameters to the taxiing performance of landing gear. The analysis shows that all of the side orifice, variable orifice and the high pressure cavity can reduce the overload and stroke of the adaptive shock absorber. The results also show that adjusting the pressure of the double cavities can reduce more overload than adjusting these volumes. The results obtained in the paper have reference value for the landing gear design of the large aircraft.
