The dynamics research on the composite undercarriage of the Unmanned Aerial Vehicle

The Undercarriage is affected by the dynamic load when the Unmanned Aerial Vehicle (UAV) taxis and lands on the ground, especially during the landing to the ground, it needs higher requirements. The dynamical deformation and strength characteristics of the Undercarriage directly determine its performance and affect the safety of the UAV. In the article, we study the dynamical deformation, the strength calculation and the experiments in order to understand whether it can meet the requirements of design and use or not. By the strength check of Tsai-Wu strength theory and ultrasonic flaw detection technology, the strength of the landing gears meets the needs of UAV.
