| 中文摘要: |
| 自激振荡可利用运动状态反馈等机制实现自主吸收环境能量，开发新型自激振荡系统可推动自适应主动机器的进一步发展。基于光热膨胀材料提出一种单摆结构，通过建立光热响应摆动力学模型，从理论上研究了单摆的光驱自激振荡现象。结果表明，单摆有静态模式和振荡模式两种运动模式。在阐明了自激振荡机理及其触发条件后，进一步全面探讨了系统参数对振动幅值和频率的影响。 |

| The self-excited oscillation can absorb environmental energy autonomously by the motion state feedback mechanism，andthe development of a new self-excited oscillation system can promote the further development of adaptive active machines.Based onthe photothermal expansion material，a simple pendulum structure is proposed.By establishing the dynamic model of the photothermalresponse pendulum，the self-excited oscillation phenomenon of the simple pendulum is theoretically studied.The results show that thependulum has two modes：static mode and oscillatory mode.After clarifying the mechanism of self-excited oscillation and its triggeringconditions，the influence of system parameters on the amplitude and frequency of vibration is further discussed comprehensively. |
