Abstract

Living organisms, such as geckos and insects, exhibit excellent climbing ability on various complex surfaces due to the hair-like hierarchical adhesive systems of their attachment devices. Over the past few decades, an increased understanding of the mechanisms of multiscale hierarchical adhesion systems and the continual improvement of theoretical modeling have promoted the rapid advancement in the design and application of biomimetic artificial adhesives. The modeling of biomimetic artificial adhesives has developed from simple structures to complex constructions with multilevel hierarchical properties. A review of advances in the development of these contact mechanics models is presented here. Adhesion and friction models considering multiscale hierarchical structural forms are discussed, with a focus on multiscale hierarchical models based on the development of the Cantor‒Borodich profiles. Finally, the most recent developments in studies of artificial setae with spatula-like ends, both axisymmetric and non-axisymmetric, are reviewed.

受生物多尺度层次结构启发的仿生人工胶粘剂的接触力学理论及应用进展
生物,如壁虎和昆虫,在各种复杂的表面上表现出优异的攀爬能力,这是由于它们的附着装置具有毛发状的分层粘附系统。在过去的几十年里,随着对多尺度分层黏附系统机理的深入了解和理论建模的不断完善,仿生人工黏附系统的设计和应用得到了快速发展。仿生人工胶粘剂的建模已经从简单的结构发展到具有多层分层性能的复杂结构。本文对这些接触力学模型的发展进行了综述。讨论了考虑多尺度分层结构形式的粘附和摩擦模型,重点讨论了基于Cantor-Borodich剖面发展的多尺度分层模型。最后,综述了轴对称和非轴对称人工刚毛的最新研究进展。
