| 摘要: |
| 为了揭示PZT-5H压电陶瓷电源复合结构在高速撞击载荷下电源外部电路中储能电容对输入电压、输入能量的影响规律，利用自行构建的一级轻气炮加载系统、电源外部电路及电输出测试系统，分别开展了长径比为1∶1的柱状弹丸在相近碰撞速度、不同储能电容容量条件下高速撞击单片和多片压电陶瓷复合结构实验。实验结果表明：储能电容越大，压电陶瓷输出电压峰值越小、储能电容充电电压越小，存储能量值越小；随着储能电容量与压电电容量比率的增大，压电陶瓷的能量转换率减小；此外，储能电容的存储能量随压电陶瓷层数的增加而增大；压电陶瓷的电容与储能电容的匹配对储能电容的输入电压和储能电容的输入能量有较大影响。 |

| Abstract: |
| In order to reveal influence of external capacitance on the voltage input and input energy provided by the PZT-5H piezoelectric ceramic composite structure under high-speed impact loading, experiments have been performed by using one-stage light gas gun loading system combining with a power supplier circuit and power output testing system, which the aspect ratio of 1:1 column projectile impact monolithic and multi-piece piezoelectric ceramic composite structure at the near impact velocity and different storage capacity. The experimental results show that the more larger storage capacitance is, the smaller the piezoelectric ceramic output voltage is. However, the smaller of the capacitor voltage is, the smaller the value of energy storage is; with the energy storage capacitance increasing, the piezoelectric capacitance ratio and the energy conversion rate of piezoelectric ceramics decreases; In addition, the storage energy capacitor increases with the increasing of the piezoelectric ceramic layers; the relationships of storage energy capacitor and piezoelectric ceramic capacitor has a great influence on the input voltage and storage energy for storage energy capacitor. |
