| 摘 要： | 跑道路面不平度y(s)的测量结果往往以数字序列{y_n}的形式给出。本文首先引入了ARMA模型分析方法,提出了路面不平离散序列{y_n}的频域与空间域模型。在离散模型的基础上,继而导出了路面不平y(s)的频域与空间域模型,这些模型不仅能很好地表征路面不平特性,而且便于对由路面不平产生的结构振动进行分析。

| Abstract: | In this paper method of ARMA time series analysis is first used in the area of modelling of runway surface rough'ness to give spectra domain model amd space domain model of runway roughness discret series {yn}. On the basis of discret models, spectra domain model and space domain model of runway roughness process y(s) are deduced. The model can not only charaterize the features of runway roughness, but also be apt to analyze the structural vibrations due to the roughness. |
