| Abstract |
Unmanned Aerial Vehicles (UAVs) have gained widespread popularity in various fields, leading to a demand for reliable and cost-effective measurement systems to ensure the safe and efficient operation ...of these UAVs. One of the vital aspects to ensure the UAV safe operation is the vibration information that occurs during the flight to detect anomalies that may be caused by failures or other factors. At the operational aspect, the vibration data that recorded during the flight test can be used to design the damper system to minimize the vibration effect during the aerial photography mission. This research proposes a low-cost vibration and impact measurement system for small electric fixed-wing UAVs. The system utilizes accelerometers to measure the vibration and impact levels experienced by the aircraft during flight. We designed and tested the system on a small electric fixed-wing UAV and compared its results with a commercial measurement system. This allows us to evaluate the accuracy and reliability. The experimental results demonstrated that our system can accurately measure the vibration and impact levels experienced by small electric fixed-wing UAVs during flight. Furthermore, our system was found to be reliable and cost-effective compared to the commercial measurement system with differences in vibration measurement in the range of 10% with some parameters even below 6%, impact measurement in the range of 2-4%, and the total cost amounts of the component is USD 62.84. This research provides a low-cost solution for monitoring vibration and impact levels of small electric fixed-wing UAVs.show more
