提出了一种在两个悬臂板上附加一个刚性框架的宽带压电能量采集器。设计了对称等截面矩形、对称变截面梯形和反对称变截面三种不同的悬臂板布置形式和截面形状。将框架视为刚体，悬臂板视为变形体，利用有限元软件ABAQUS计算了结构的固有频率、振型和输出电压。结果表明，由刚性框架包围的反对称梯形悬臂板具有较低的固有频率，在低频范围内有较多的工作频带，输出电压最高。根据仿真结果，加工出由刚性框架包围的反对称梯形悬臂板的PEH样机，并使用定制夹具将其固定在振动台上。通过扫频试验，用示波器测量了不同频率下PEH的开路输出电压，得到了PEH的前三阶固有频率。结果满足了低频范围内多阶固有频率和高输出电压的设计要求。该研究为PEH的工程应用提供了理论和实验依据。
Attaching a rigid frame to two cantilever plates, a compact piezoelectric energy harvester (PEH) with wide bandwidth is proposed in this paper. Three different arrangement form and section shape of the two cantilever plates, such as, symmetrical uniform section rectangle, symmetrical variable section trapezoid and anti-symmetrical variable section are designed. Considering the frame as a rigid body and the cantilever plate as a deformed body, natural frequencies, modes and output voltages of the structures are calculated using finite element software ABAQUS. It is found that the anti-symmetrical trapezoidal cantilever plate surrounded by rigid frame, has lower natural frequency, more working frequency bands in low frequency range and the highest output voltage. According to the simulation results, prototype of PEH with anti-symmetrical trapezoidal cantilever plate surrounded by rigid frame is processed and fixed to the vibration platform using custom fixture. Through sweep test, open-circuit output voltage of PEH at different frequencies is measured using oscilloscope and the first three order natural frequencies are obtained. The results meets the design requirements of multilevel natural frequency and high output voltage in low frequency range. This research provides theoretical and experimental basis for the engineering application of the PEH.
