In this paper, we propose an innovative light-powered LCE-slider system that enables continuous self-circling on an elliptical track and is comprised of a light-powered LCE string, slider, and rigid elliptical track. By formulating and solving dimensionless dynamic equations, we explain static and self-circling states, emphasizing self-circling dynamics and energy balance. Quantitative analysis reveals that the self-circling frequency of LCE-slider systems is independent of the initial tangential velocity but sensitive to light intensity, contraction coefficients, elastic coefficients, the elliptical axis ratio, and damping coefficients. Notably, elliptical motion outperforms circular motion in angular velocity and frequency, indicating greater efficiency. Reliable self-circling under constant light suggests applications in periodic motion fields, especially celestial mechanics. Additionally, the system's remarkable adaptability to a wide range of curved trajectories exemplifies its flexibility and versatility, while its energy absorption and conversion capabilities position it as a highly potential candidate for applications in robotics, construction, and transportation.
在本文中，我们提出了一种创新的光驱动液晶弹性体滑块系统，该系统能够在椭圆形轨道上持续自循环，由光驱动液晶弹性体绳、滑块和刚性椭圆形轨道组成。通过建立和求解无量纲动力学方程，我们解释了静态和自循环状态，重点强调了自循环动力学和能量平衡。定量分析表明，液晶弹性体滑块系统的自循环频率与初始切向速度无关，但对光强度、收缩系数、弹性系数、椭圆轴比和阻尼系数敏感。值得注意的是，椭圆运动在角速度和频率方面优于圆周运动，表明效率更高。在恒定光照下可靠的自循环表明其在周期性运动领域有应用，特别是天体力学。此外，该系统对广泛的弯曲轨迹具有显著的适应性，体现了其灵活性和通用性，而其能量吸收和转换能力使其成为机器人技术、建筑和交通运输领域应用的极具潜力的候选者。
