| 中文摘要: |
| 液晶弹性体（LCE）梁在移动光照作用下会产生弯曲动态响应，为此建立 LCE固支梁在移动光照下的动态模型，并推导出动态响应的控制方程。在此基础上，通过模态叠加法和Duhamel积分法获得LCE固支梁在移动光照下动态响应的解析解，并利用Matlab软件对模型进行编程进而分析物理参数对LCE固支梁动态响应的影响。结果表明：当移动光照的速度达到一阶临界速度时，固支梁跨中动态响应的振幅最大。此外，通过改变光照强度、LCE的材料收缩系数和阻尼系数等参数，可以有效调控动态响应。研究成果在软机器人、智能控制和能量转换等领域具有应用价值。 |

| Liquid crystal elastomer (LCE) beams produce a bending dynamic response under the moving illumination. The dynamic model of LCE fixed supported beam under moving illumination was established, and the control equation of dynamic response was derived. On this basis, the analytical solution of the dynamic response of LCE fixed supported beam under moving illumination was obtained by modal superposition method and Duhamel integral method, and the dynamic response was programmed by Matlab software to analyze the influence of physical parameters on the dynamic response of LCE fixed supported beam. The result showed that the maximum amplitude of the dynamic response on the mid-span of the fixed supported beam reached the peak only when the velocity of the moving illumination reaches the first-order critical velocity. In addition, the dynamic response can be effectively controlled by the light intensity changes, the shrinkage coefficient and the damping coefficient of LCE material. The results can be applied to the fields including soft robotics, intelligent control and energy conversion. |
