| 中文摘要: |
| 在分析了形状记忆合金双程记忆效应原理的基础上，采用铜锌铝双向记忆合金片，设计并加工制作了两种微小型光热驱动马达，对其进行了驱动实验研究。研究结果表明，用输出波长为1064nm的YAG脉冲激光作为光热驱动马达的驱动源，在适当的输出功率和频率下，棘轮棘爪型光热驱动马达可获得较精确的步距，齿轮传动型光热驱动马达可获得较高的转速。这类用激光作为驱动源的微小型光热驱动马达易于小型化，真正实现无线遥控，有望在微光机电系统获得广泛应用。 |

| On the basis of analyzing the principle of two-way memory effect of the shape memory alloy, two miniature optothermal motors are designed and manufactured using sheets of Cu-Zn-Al two-way shape memory alloy. Experiments are carried out to test their driving performance. The experiment results demonstrate that when using a 1064nm YAG pulsed laser with an appropriate output power and frequency as the motors’ driving source, the ratchet-pawl-type optothermal motor can have a precise step distance and the gear-type optothermal motor can have a high rotational speed. This kind of optothermal motors could be integrated and widely utilized in micro-optical-electro- mechanical systems wirelessly with remote controlling. |
