摘要:
我们研究了在粘性流体中摆动的、具有新型曲率相关弯曲刚度的细长丝。数值与实验研究表明,这种差异化刚度可沿柔性长丝维持远距离传播的平面弯曲波,这与需要更复杂控制的均匀刚度情况形成鲜明对比。我们特别证实,基部驱动是产生高振幅平面弯曲波的可行且简约的机制。此外,由此产生的摆动模式与纤毛等具有推进功能的生物丝的“动力-恢复”冲程高度相似,在机器人与工程系统中具有广泛应用前景。
英文摘要:
We study a slender filament beating in a viscous fluid with novel curvature-dependent bending stiffness. Our numerical and experimental investigations reveal that such differential stiffness can sustain planar bending waves far along flexible filaments, in stark contrast to the uniform-stiffness case which requires more sophisticated control. In particular, we establish basal actuation as a viable, parsimonious mechanism for generating high-amplitude planar bending waves. Moreover, the resulting beat patterns closely resemble the power-and-recovery strokes of propulsive biological filaments such as cilia, suggesting extensive applications in robotic and engineered systems.
