| 英文摘要 | 提出一种由悬臂梁和分布式压电片构成的可调频压电俘能结构,改变压电片的电场边界条件可改变俘能结构的共振频率,对该结构下的两种不同的压电片结合形式进行了AnSyS仿真验证与比较。结果表明,使用嵌入式结合形式比使用表面粘贴式结合形式可得到更高的频率变化率,频率相对变化率可达3.17%。; This research proposes a novel piezoelectric scavenger structure which is constructed by a cantilever base beam and piezoelectric elements bonded with the base beam in a certain manner.By changing the electrical boundary conditions of the piezoelectric elements,the resonant frequency of the beam structure changes accordingly.Two kinds of manners in which piezoelectric elements are bonded with the beam are investigated and compared with ANSYS simulations.The results show that the embeded manner surpasses the surface-bonded manner with the frequency variation ratio of 3.17%.; 国家自然科学基金资助项目(11202176) |
