Coordination in Coupled Arrays of Stiff Filaments—Modelling and Simulation
Mathematics ( IF 2.4 ) Pub Date : 2020-08-03 , DOI: 10.3390/math8081282
Davide Spinello

We present the mechanical model of an array of elastic filaments and simulate the response with different mechanical couplings. This class of systems is inspired by robust and elegant solutions for locomotion mechanics that have emerged in several small-scale biological entities in the form of beating protrusions, such as cellular cilia and eukaryotic flagella. The collective dynamics of cilia arrays reveals important features such as array alignments, two-phase asymmetric beating of individual filaments, and the emergence of metachronal coordination, which make them suitable for bio-inspired terrestrial and aquatic locomotion. The model presented here is the basis for further developments towards the design of terrestrial and aquatic locomotion systems for general purpose robotic devices.

硬丝耦合阵列中的协调—建模与仿真

我们介绍了弹性细丝阵列的力学模型,并模拟了不同机械耦合的响应。此类系统的灵感来自于运动力学的强大而优雅的解决方案,这些解决方案以跳动突起的形式出现在几个小规模的生物实体中,例如细胞纤毛和真核鞭毛。纤毛阵列的集体动力学揭示了重要的特征,例如阵列排列,单个细丝的两相不对称跳动以及异时协调的出现,使它们适合于生物启发的陆地和水上运动。此处介绍的模型是进一步发展通用机器人设备的陆地和水上运动系统的基础。
