摘　　要：同步存在于自然界的每一个角落,这是值得探索的,而自激振动具有主动收集环境能量、自主性、便携性等优点。鉴于此,提出了基于液晶弹性体(LCE)纤维与普通弹簧组成的光驱动自激耦合振动系统,从理论上研究了两个自激耦合振子在系统参数影响下同步的可能性。发现在稳定的光照条件下,由于两个耦合振子间的相互作用,系统的自激振荡有三种同步模式:静态模式、同相位模式和反相位模式。研究结果将加深对自激耦合振子同步行为的理解,并在能量收集、软机器人、信号检测、主动电机和自维持机械中具有潜在的应用。Synchronization exists in every corner of nature, which is worth exploring, and self-excited vibration has the advantages of active collection of environmental energy, autonomy, portability and so on.In view of this, a light-driven self-excited coupled vibration system based on liquid crystal elastomer(LCE) fiber and common spring is proposed. It is found that the self-excited Oscillation of the system has three synchronous modes: static mode, in-phase mode and anti-phase mode due to the interaction between the two coupled oscillators under stable illumination. The results will deepen the understanding of the synchronization behavior of the self-excited coupled oscillators and have potential applications in energy collection, soft-robot, signal detection, active motor and self-sustaining machinery.
