论文摘要
通过在弹性微温材料的两个自然长度之间实现耦合效果，提出了自主三个球体微型机器人的模型。这种耦合机制是由先前在振荡器系统中同步现象的模型的动机。我们从数值上表明，微型威格斯可以获得非零的稳态速度和自然长度振荡之间的有限相位差。这些速度和相位差几乎与初始相位差无关。耦合参数的有限范围，微型威格斯可以具有自动定向运动。为了确定其分叉结构，对相位差的稳定性进行了研究。
A model of an autonomous three-sphere microswimmer is proposed by implementing a coupling effect between the two natural lengths of an elastic microswimmer. Such a coupling mechanism is motivated by the previous models for synchronization phenomena in coupled oscillator systems. We numerically show that a microswimmer can acquire a nonzero steady state velocity and a finite phase difference between the oscillations in the natural lengths. These velocity and phase difference are almost independent of the initial phase difference. There is a finite range of the coupling parameter for which a microswimmer can have an autonomous directed motion. The stability of the phase difference is investigated both numerically and analytically in order to determine its bifurcation structure.
