| 摘 要： | 为了研究压电陶瓷驱动器的驱动性能,分析了以PZT-5H为驱动元件的叠堆型驱动器,采用简化的等效器件建立了电学模型。基于压电陶瓷材料的机电耦合特性运用ANSYS有限元分析软件对叠堆型驱动器进行了计算分析,得出输入电压与输出位移呈近似线性关系,通过控制压电陶瓷两端电压来控制其位移。仿真结果验证了此方案的有效性和可行性。该驱动器在自适应弹药上具有潜在的应用价值,可为弹头的偏转驱动装置设计提供参考。

| Abstract: | A stack-type of actuator with PZT-5H as actuate element was presented.To study its driving performance characteristics of piezoelectric ceramic actuators,an electrical analysis model using equivalent structure was built.Based on the electromechanical coupling characteristics of piezoelectric ceramic materials,the numerical calculation on stack-type actuator was carried out with analysis of FEA software,the relationship nearly linear between the input voltage and the output displacement was obtained,which co... |
