摘　　要：飞机在地面滑跑过程中产生的振动严重威胁着飞机起降安全。针对新型轮橇式起落架飞机在滑行时受到地面随机激励而产生剧烈振动的问题,本文在多体动力学软件LMS Virtual.Lab Motion中建立了轮橇式起落架飞机全机着陆滑跑动力学模型,基于高斯白噪声经典随机过程建立随机道面激励模型,在MATLAB/Simulink中设计了半主动控制缓冲器,通过LMS Virtual.Lab Motion与MATLAB的联合仿真方法,分析对比了缓冲器被动减振、半主动PID控制和半主动模糊PID控制三种控制律作用下轮橇式飞机的滑行振动特性。研究结果表明,所设计的模糊PID半主动控制缓冲器,能够有效减小机体垂向振动位移和垂向载荷,并且可消除飞机刹停后的动态误差,使飞机更快达到静止状态。通过多工况仿真验证了该控制方法的适应性和有效性。The vibration caused by the aircraft running on the ground seriously threatens the safety of the aircraft taking off and landing.To solve the problem of the severe vertical vibration on an aircraft with wheel-ski main landing gears caused by the random runway during the taxiing process,the full-aircraft landing and running model of the wheel-ski landing gear is established in a multi-body dynamic software LMS Virtual.Lab Motion.The stochastic runway model is established based on the Gaussian white noise classical stochastic process.Then a semi-active control shock absorber in the wheel-ski landing gear is designed in MATLAB/Simulink.Using the co-simulation method of Motion and MATLAB,the taxiing vibration characteristics of the wheel-ski landing gear aircraft are analyzed and compared under the control of the passive shock absorbers,the semi-active PID shock absorbers and the semiactive fuzzy-PID shock absorbers.The results show that the designed semi-active fuzzy-PID control shock absorber can effectively reduce the vertical vibration amplitude and load.Also,the aircraft can reach a static state more efficiently.The adaptability and effectiveness of the proposed control method is verified by the simulation under multiple working conditions.
