Abstract: Compared to traditional runways, compacted snow runways exhibit a reduced surface smoothness and modulus, leading to intensified dynamic responses during aircraft taxiing. This study establishes an aircraft-snow runway interaction model using ANSYS software to quantitatively analyze the effects of the runway wavelength, amplitude, modulus, and aircraft taxiing speed on system dynamics. The results of the study are largely in agreement with the results computed by the ADAMS dynamic analysis software. Specifically, as the wavelength-to-wheelbase ratio increases, the peak acceleration of the landing gear and runway surface decrease rapidly and then gradually stabilise, while the peak runway strain first increases rapidly and then stabilises. As the amplitude increases, the peak acceleration of the landing gear and runway surface continuously increase. Furthermore, the peak vertical strain of the runway decreases. As the runway modulus increases, the peak acceleration of both the landing gear and the runway, as well as the peak runway strain, continuously decrease. With increasing aircraft speed from 2 to 30 m/s, the peak landing gear acceleration rises sharply, while the peak runway acceleration increases correspondingly. The findings of this study offer valuable theoretical guidance for the design and construction of snow-covered runways. [ABSTRACT FROM AUTHOR]
