摘要
为了解壁虎的黏着爬行机制,分别对纳米仿壁虎刚毛结构与光滑和粗糙表面间的接触情况进行了建模,并用MATLAB仿真得出仿壁虎刚毛产生的黏着力与刚毛的几何结构和材料之间的关系。仿真结果表明,弹性模量和刚毛长度越大,表面粗糙度和刚毛半径越小,仿壁虎刚毛阵列结构产生的黏着力越大。
In order to study the adhesion of the gecko ＇ s foot, contact relation between biomimetic gecko seta structure and the smooth and rough surface was modeled. Relationship between the gecko adhesive force and the geometry and material properties was simulated by MATLAB. The simulation results show that the adhesive force produced by biomimetic gecko seta array structure increases with the increase of elastic modulus and seta length, and with the decrease of surface roughness and radius of seta.
