QUADCOPTER BODY FRAME MODEL AND ANALYSIS

Quadcopter frame modeling is useful to analyze the reliability of body frame part and to help determine the type of rotor and propeller in order to assure the necessary flight acceleration. Quadcopter flight stability is influenced by the resulting thrust, by the distance between each rotor propeller and also by the frame rigidity; the frame has been designed to be as light as possible, meanwhile maintaining the strength to carry the load. Solidworks software has been used to design and analyze using Finite Element Analysis (FEA) method the quadcopter frame - having folded size of 560 (mm) square - also a 406x127 (mm) propeller and rotor's angular velocity and air flow produced around the propeller. The FEA method showed that the presence of rotational velocities in each propeller flow field will significantly affect the thrust efficiency which can cause flight instability or body frame vibration.
