Vibration damping design for unmanned aerial vehicles

As the application areas of Unmanned Aerial Vehicles (UAVs) increase, the number of equipment they carry increases depending on the tasks they will perform. In order to ensure both the safety of these equipment and the accuracy of the tasks, data is received from the sensors built on the vehicle. However, the accuracy of the data obtained from on-board sensors is degraded due to mechanical vibrations. Elimination of this negative effect caused by vibration will prevent possible errors, therefore preventing vibration becomes an important issue for UAVs. In this thesis, vibration damper designs are proposed for UAVs. The sources of vibrations on a Single Rotor Rotary Wing (Monocopter) type UAV have been identified. In this thesis, damping performance comparisons were made by performing vibration test setup tests of the designed dampers. In the thesis, according to the measurement results made at 3 different speed stages, the damper which is named G2S2 was respectively; first speed stage; 66% for the X-axis, 77% for the Y-axis, 84% for the Z-axis, second speed stage; 81% for the X-axis, 84% for the Y-axis, 97% for the Z-axis; third speed stage; 85% for the X-axis, 84% for the Y-axis, 98% for the Z-axis with the above damping performance values, it was the damper with the highest performance.
