摘要
This paper presents a detailed investigation into piezoelectric energy harvest-ing for Unmanned Aerial Vehicles(UAVs)through advanced computational modeling and simulation.The study focuses on optimizing the integration of piezoelectric materials(PZT-5H)into UAV wings to convert mechanical vi-brations-induced by aerodynamic forces-into usable electrical energy.A high-fidelity 3D model of a DJI Mini 3 Pro quadcopter was developed,and Finite Element Analysis(FEA)combined with Computational Fluid Dynam-ics(CFD)was employed to assess energy harvesting efficiency under varying flight conditions.Key findings indicate that optimal placement of piezoelec-tric patches near high-stress zones yields voltage outputs ranging from 1.54 V to 24.3 V with peak performance near resonant frequencies.The study also explores the impact of structural modifications,such as adding a steel fin,to enhance vibration transmission.
