摘　　要：起落架缓冲器是飞机起落架的重要组成部分之一,其性能的好坏直接影响到飞机起降的安全性。本文建立了基于磁流变液的飞机起落架缓冲系统的动力学模型,并用开关控制算法与模糊控制算法完成某型飞机起落架缓冲系统的缓冲控制,与被动式缓冲系统的缓冲效果进行了比对分析,验证了提出的半主动缓冲控制系统的减震效果优于传统的被动式缓冲系统。仿真结果表明,采用的开关控制和模糊控制实现了冲击载荷能量的有效吸收。The landing gear buffer is one of the most important parts of aircraft landing gear, it will directly affect the safety of the aircraft take - off and landing. The dynamic model of aircraft landing gear system is established based on the magneto - rheological fluid, the buffer control in an aircraft landing gear with on - off control and fuzzy control algorithms are completed. Compared with the buffering effect of passive buffer system, the damping effect of the proposed method with semi - active on - off control and fuzzy control is better than the traditional passive buffer system. Simulation results show that the semi - active on - off control and fuzzy control can complete the absorption of impact energy effectively.
