摘要	Trapezoidal cantilever beams are applied as the piezoelectric energy harvester of multicantilever beams to widen the operating frequency bandwidth and improve energy harvesting efficiency under low-amplitude excitation frequency. The resonant frequency and transfer function of the system are calculated in accordance with the three-dimensional scale and additional mass at the free end of cantilever beam and deduced through the equivalent processing of the bimorph and the elastic base beam to establish the mathematical model of the transverse vibration of the trapezoidal cantilever beam. The model of the composite trapezoidal piezoelectric energy harvester system is derived on the basis of this analysis. Results show that the composite trapezoidal cantilever beams structure can effectively widen the working frequency band and facilitates resonance matching with the environmental vibration frequency to improve power generation efficiency. This work is an important reference for optimizing the design and application of the energy harvesters of multicantilever beams. © 2019, Editorial Department of Journal of HEU. All right reserved.
