Abstract: In order to study the anti-sliding performance of the aircraft in the runway, a finite element analysis method is used to establish a finite element model of the contact between the aircraft wheel and the road sur-face. The vertical deformation of tire under aircraft ｌｏａｄ is analyzed and compared with empirical formula to verify the feasibility of the model. Then the adhesion coefficient is used as the anti-sliding evaluation index, and the influence of aircraft speed, tire ｌｏａｄ, tire tire pressure and water film thickness on the adhesion coeffi-cient is analyzed by model. The specific conclusions for this study are as follows: The adhesion coefficient between the tire and the pavement decreases with increasing speed, increases as the tire ｌｏａｄ increases, and decreases as the tire pressure increases. The adhesion coefficient decreases with the increase of water film thickness, and when the water film thickness is small, the adhesion coefficient decreases more obviously with the increase of velocity.
