Experimental and Numerical Modal Analysis of an Unmanned Aerial Vehicle’s Composite Wing

Popis výsledku v původním jazyce

This article investigates the structural dynamics of a UAV composite wing through FEM simulations and experimental modal analysis, aiming to replace traditional experimental testing in UAV structural evaluations. The simulations, performed with Ansys Composite Prep/Post (ACP), model each composite layer with specific fiber orientations, material properties, and thickness. Experimental tests, utilizing a shaker for excitation and an accelerometer for response measurement, were conducted on the aircraft in the frequency range of 0 to 1100 Hz, targeting operationally relevant harmonic frequencies. A comparative analysis between simulation and experimental results identifies sources of discrepancies, particularly in critical low-frequency modes essential for UAV performance. The study highlights how simplifications in the FEM model, such as excluding control surfaces and assuming material homogeneity, impact simulation accuracy. The paper concludes by outlining directions for further research, stressing the need to refine FEM models and enhance composite material representations to improve UAV reliability and simulation accuracy.
