Abstract

In this paper, a bidirectional micro-device based on multi-electrothermal co-actuation is proposed for a fuze safety system, combining the advantages of the simple structure, small size, low input voltage, large output, and absence of electromagnetic interference in electrothermal actuators. Based on the working principle of the multi-electrothermal co-actuation device and the mathematical model of the single V-shaped electrothermal actuator established in this paper, the temperature distribution of the V-shaped electrothermal actuator is simulated. In addition, the dynamic response and the effect of geometric factors on the output performance of the multi-electrothermal co-actuation device are analyzed in detail. Furthermore, driving characteristics tests of the electrothermal micro-device are carried out. The experimental findings indicate that a displacement of approximately 258.95 μm with a response time of about 156.51 ms can be achieved by the V-shaped electrothermal actuator when the applied voltage is 1.2 V. In a single cycle, a total displacement of 340 μm is obtained by the co-actuation device in around 1.28 s.

基于多电热协同驱动的双向微器件设计与驱动特性研究。

本文结合电热致动器结构简单、体积小、输入电压低、输出大、无电磁干扰等优点，提出了一种基于多电热共致动器的双向微型引信安全系统。基于多电热共致动装置的工作原理和本文建立的单个v型电热致动器的数学模型，对v型电热致动器的温度分布进行了仿真。此外，还详细分析了多电热共作装置的动态响应和几何因素对输出性能的影响。此外，还对电热微器件进行了驱动特性测试。实验结果表明，当施加电压为1.2 V时，V型电热致动器的位移约为258.95 μm，响应时间约为156.51 ms。在单周期内，共驱动装置在1.28 s左右获得340 μm的总位移。
