| 摘 要： | 提出并研究了一种新型阵列式Cymbal俘能器.该俘能器由多个独立Cymbal圆周阵列而成,特别适用于大面积振动源的能量收集.基于压电方程,推导出该阵列式Cymbal俘能器的开路电压和俘获电能的数学模型.理论分析该阵列式Cymbal的压电发电装置所输出的开路电压与单个Cymbal的电压相等,而所输出的电功率是单个Cymbal的n倍.有限元计算证明了该模型的正确性.

| Abstract: | A new type of array Cymbal piezoelectric harvester is presented in this paper. The harvester is composed of several independent circular arrays of Cymbal. This harvester is especially suitable for large area source of vibration energy harvesting. Based on piezoelectric equation, the mathematical model of open-circuit voltage and power for array Cymbal harvester is derived.From theoretical analysis, the open-circuit voltage of the array Cymbal harvester equals to a single cymbal and the output power is several times of a single cymbal. Finite element calculation proves the correctness of the mathematical model. |
