Aircraft wheels-up landing refers to the minor crash landing conditions under the controlled state. It is needed to analyze the deformation of the ground part of the wheels-up landing in the preliminary design stage of civil aircraft, so as to provide input to the system layout and avoid the risk of fire. In this paper, a method is proposed to analyze the influence area of the landing structure of wheels-up landing, which is suitable for the preliminary design stage of civil aircraft. The stiffness of the landing part is simulated by the refined finite model of the fuselage, and the actual deformation of the wheel during the landing process is simulated by the elastic beam element model of the aircraft. Finally, the deformation area of the body structure is obtained in the refined finite model of the landing area. This method can be applied to the engineering project of civil aircraft design.
