以双向环形耦合Duffing振子系统为对象, 研究脉冲信号激励下耦合振子间动力学行为变化特征时, 发现其与单向环形耦合Duffing振子系统类似, 在一定的参数条件下, 脉冲信号能引起其中一个振子与其他振子运动轨迹间出现短暂失同步的现象即瞬态同步突变现象. 基于这种现象, 提出了一种微弱脉冲信号检测的新方法, 用于检测强噪声背景中的局部放电脉冲信号. 实验测试表明, 利用本文方法对不同放电电极的局部放电脉冲信号进行检测时, 在低信噪比条件下可取得良好的检测效果, 进而扩展了现有的Duffing振子对非周期信号的检测范围及应用领域.

Bidirectional ring-coupled Duffing oscillator hasbeen investigated. A phenomenon is discovered, showing that when one of the oscillators is driven by pulsed signal under certain parameter conditions, this and the other oscillators will suddenly change from synchronization to transient non-synchronization and then rapidly return to synchronization, which is defined as transient synchronization mutation in this paper. This phenomenon is used to accurately detect partial discharge signal in strong noise environments. The experimental tests show that this method achieves good detection effect in low SNR for partial discharge signal of different discharge electrode, which can further extend the weak signal detection range based on Duffing oscillator.-
