摘　　要：飞机滑跑时会受到跑道不平整作用而引起随机振动,不仅会影响飞机着陆滑跑过程中乘客的舒适性,更会造成起落架结构损伤带来安全隐患。因此,研究飞机滑跑系统在不平整跑道上滑跑的动力学行为具有重要的理论价值和现实意义。本文基于飞机滑跑系统动力学模型的结构特点,重点探讨了非线性飞机滑跑系统从二质量块模型、多自由度模型到多体系统模型的发展变化。考虑跑道不平整对系统所带来的影响,详细梳理了不平整跑道的描述方法,而后为得到合理的外部载荷,从频域的功率谱方法和时域的谐波叠加法出发,分析不平整跑道对飞机滑跑系统的影响。最后,基于飞机滑跑系统的发展和在滑跑过程中所面临的问题,总结提出了复杂结构和环境对飞机滑跑动力学建模与影响分析的未来研究方向。The random vibration caused by the unevenness of the runway will not only affect the comfort of passengers during the landing,but also cause the damage of the landing gear structure and bring safety risks.Therefore,it is of great theoretical value and practical significance to study the dynamic behavior of the aircraft running system on the uneven runway.Based on the structural characteristics of the dynamic model of the aircraft skid system,this paper focuses on the development of the nonlinear aircraft skid system from the two-mass model,the multi-degree of freedom model to the multi-body model.Considering the influence of the uneven runway on the system,the description method of the uneven runway is sorted out in detail.Then,in order to obtain reasonable external load,the influence of the uneven runway on the aircraft skid system is analyzed from the power spectrum method in the frequency domain and the harmonic superposition method in the time domain.Finally,based on the development of aircraft skid system and the problems faced in the process of skid,the future research direction of complex structure and environment on aircraft skid dynamics modeling and analysis is summarized.
