摘要
根据线性梁理论,针对仿壁虎粘附阵列与服从高斯分布的粗糙表面,分别建立了在动态粘附接触与动态脱离过程中二者相互作用力模型.基于合理的参数选择,讨论了该作用力与二者间的间距、预压力及夹角等因素的关系,并得到仿真结果.这一研究为仿壁虎纳米粘附阵列的设计提供理论参考.
Based on the linear cantilever beam theory and the Gaussian height distribution of rough surface, theoretical contact models of interaction force during dynamic attachment and detachment on rough surface were constructed. Meanwhile, by making a reasonable choice of the parameters, the relationships between the interaction force and the separation, preload and angle of the attachment and detatchment were discussed in detail. It may provide a theoretical reference for designing a better mimicking gecko adhesion array.
