| description | The application of semi-active control technology on landing gear is mostly limited to single or magnetorheological landing gear. The research on the whole aircraft is more valuable for the practical application of semi-active control. LMS Virtual.lab Motion is used to establish a virtual model of the whole aircraft. Taking the singlechamber oil-gas buffer as the research object, the mechanical models of passive control and semi-active control are analyzed, and the oil-gas buffer simulation model is built in AMESim. Based on the fuzzy control theory and variable damping throttle semi-active control principle, a fuzzy controller is designed in MATLAB/Simulink, and the controller model is integrated into AMESim to realize real-time control of the orifice. Through the 3D-1D co-simulation of mechanical, hydraulic and control, the simulation results of the whole aircraft drop dynamics under passive control and semi-active control are analyzed. The results show that the semi-active control responds quickly, the peak vertical loads of the nose and main landing gear buffer struts is reduced by 20.5% and 13.1% respectively, and the buffering efficiency is also higher than that of passive control. The peak vertical acceleration of the fuselage is reduced by 23.2%, and the vibration is stabilized faster, which can improve the ride comfort. |
