Review of Dynamic Model of Aircraft Taxing on Uneven Runways
摘要
Abstract
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.关键词
