【摘要】 利用随机激励的耗散的Hamilton系统理论对飞机地面滑跑时动力学性能进行了分析。首先利用Hamilton原理建立了飞机地面滑跑的起落架分析模型,根据该模型求出了系统响应的转移概率密度所服从的FPK方程,通过解响应的转移概率密度所服从的FPK方程,求出了方程的精确平稳解,由此得出了边缘概率密度。工程算例表明,得用该方法可直接求出系统响应的边缘概率密度,同时该模型对于分析系统的其他性能具有重要的意义。更多还原

【Abstract】 a novel approach for the analysis of non stationary response of aircraft landing gear taxiing over an unevenness runway was explored,which is based on the theory of dissipative Hamilton systems under stochastic excitation.Firstly,the analyzed model of aircraft landing gear taxiing over an unevenness runway was built by Hamilton principle.Then the FPK equations were proposed based on the model and the probability density was educed.A example was worked out to illustrate the proposed method.更多还原
