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 a safety guarantee for aircraft landing. The virtual prototype model of landing gear of a certain type of aircraft in ADAMS / Aircraft is given, and the sliding mode control algorithm of landing gear based on magnetorheological fluid is designed and implemented. The aircraft landing gear is completed by MATLAB / Simulink and ADAMS Landing buffer co-simulation analysis. Through the co-simulation, the displacement-time curve, speed-time curve, damping force-time curve and other characteristic data of the buffer are obtained. Compared with the passive landing gear cushioning performance, it is verified that the designed sliding mode control algorithm can effectively improve the performance of the aircraft Landing landing buffer performance.
