Random Vibration Fatigue Analysis of Rotor UAV Folding Propeller Hub
The hub of the folding propeller of the rotor UAV(unmanned aerial vehicle)is an important struc-ture for connecting the folding propeller with the motor.Random vibration caused by motor propeller is the main reason for the failure of hub structure.Modal analysis and random vibration analysis were conducted for vibra-tion fatigue analysis of the hub by using the finite element analysis software ANSYS.Compared with the simula-tion results,the structure of the hub was optimized and improved.The fatigue life calculation and flight test of the hub structure were carried out to verify the reliability of the design method.The design method can be ap-plied to the design of connecting parts in various rotor UAV products.
