仿壁虎刚毛阵列对卫星表面吸附能力模型与计算

Adsorption Capacity Model and Calculation of Simulated Gecko Bristle Array to Satellite

壁虎脚的粘着机理对航天机器人脚掌的研制和开发具有重要启发意义.通过单根刚毛与光滑表面黏着力模型与计算、卫星粗糙表面分布模型与接触概率与计算、刚毛阵列与卫星粗糙表面黏着力模型与计算等,分析仿壁虎刚毛阵列对卫星表面的吸附能力,发现在一定条件下仿壁虎刚毛阵能够在太空失重环境中黏着在卫星表面,对航天舱内爬行机器人、管道机器人的研制和开发具有重要的启示意义.

The adhesion mechanism of gecko foot is of great significance to the development of space robot foot.In this paper,based on the adhesion model between a single seta and smooth surface,the distribution model of satellite rough surface,the contact probability and adhesion model between the seta and satellite rough surface,the adsorption capacity of gecko bristle array to satellite surface is calculated and analyzed.It is found that under certain conditions,simulated gecko bristle array can adhere to the satellite surface in the weightlessness environment of space.It is of significance for the research and development of the climbing robot and pipeline robot in space.
