Impact Damage Analysis of Skid Landing Gear of the UAV

In this paper, by analyzing the structure and material characteristics of skid landing gear, the skid landing gear model is established by using CATIA software. In the explicit dynamic analysis type of ANSYS software, the force comparison between the impact surface of soil material and the impact surface of rigid material is made, combined with the change of momentum and energy in the process of touching the ground. This explains the necessity of landing drones on soft landing surfaces such as soil. In addition, LS-DYNA was used to simulate the dynamics of landing gear, and the strength of landing gear was analyzed according to failure criterion.
