复合L形宽频压电悬臂梁的建模与仿真
Modeling and Simulation Analysis for a L-shaped Wideband Piezoelectric Cantilever Beam
摘要
Abstract
In order to improve the transfer efficiency of the traditional single-frequency piezoelectric cantilever beam used in the energy harvesting technologies (EHT),an L-shaped piezoelectric cantilever beam,which was composed by a horizontal beam and a vertical beam,was proposed to wideband the frequency performance.The frequency-band was expanded by optimizing the structure and material parameters to reduce the distance between the 1st modal frequency and the 2nd modal frequency.The frequency equation and the vibration equation were derived according to Lagrange function and modal assumed method.The effects of the structure and material parameters on the frequency characteristics and the vibration characteristics were studied by numerical simulations.关键词
