摘　　要：飞机起落架是飞机起落的安全保证。给出了在ADAMS/Aircraft中建立某型飞机起落架的虚拟样机模型,设计并实现基于磁流变液的飞机起落架滑模缓冲控制算法,通过MATLAB/Simulink和ADAMS完成了该型飞机起落架着陆缓冲联合仿真分析。经过联合仿真得到缓冲器的位移-时间曲线,速度-时间曲线,阻尼力-时间曲线等特性数据,通过与被动式起落架的缓冲性能进行比较,验证了设计的滑模控制算法能够有效提高飞机起落架着陆缓冲性能。Aircraft landing gear is safety guarantee for air passenger when aircraft is rising and falling. The virtual prototype model of an aircraft landing gear is established in ADAMS / Aircraft in this paper. The sliding mode control algorithm based on magneto-rheological fluid is designed and implemented on aircraft landing gear. The aircraft landing gear Co-Simulation was completed with MATLAB/Simulink and ADAMS. The aircraft landing gear co-simulation obtain characteristic data , displacement- time curve, velocity - time curve, damping force - time curve , and compared with the passive landing gear cushioning properties. The sliding mode control algorithm can effectively improve aircraft landing gear cushioning properties.
