采用小波理论对机场刚性跑道平整度进行分析。针对某机场道面,采用Matlab对其纵断面信号进行小波变换分解,得到不同高频下机场刚性道面纵断面长波和短波的具体波动幅度和位置,可作为国际平整度IRI的一种补充,为航空器-机场道面相互作用动力学分析创造条件。
Using the wavelet theory to analyze the smoothness of the rigid runway in the airport. Aiming at the airport pavement, using MATLAB to decompose the longitudinal section signals by wavelet transform, the specific amplitude and position of long and short wave of longitudinal section of airport rigid pavements at different high frequencies can be obtained, which can be used as a complement to IRI of international flatness. It provides the conditions for aircraft-airport pavement interaction dynamics analysis.
