dc.description.abstract | Structural stability analysis of a high maintenance lift mounting an unmanned aerial vehicle (UAV) like a scissor lift was carried out. The dynamic test of UAV requires the maintenance lift. However, while the dynamic test was being carried out, a gust load in the form of random wind force and normal wind force could affect the dynamics and stability of the maintenance lift. Moreover, the gust load can have a frequency effect (0Hz~5Hz), and it can damage the safety of the maintenance lift and the UAV. Therefore, we constructed the symmetric four cables in order to prevent the destruction of the UAV test system by the rotating moments induced by the wind behavior. Based on the simulation results, we found that the yield strength of the steel cable with a diameter of 10 mm was sufficient to bear the rotating load considering the safety factor of 3, but the cable connection point between the cable and ground was adversely affected. Therefore, we additionally analyzed the rope tension and computed reaction forces at connection points to propose the optimal connection force with safety factor of 3. | - |
