基于鲫鱼吸附原理的仿生吸盘设计与性能分析

针对现有仿生吸盘主要应用于干燥环境的现状，对鮣鱼吸盘吸附机理进行探究，运用仿生学原理和负压吸附原理，设计出一种椭圆状外形的仿生吸盘，并分别从吸附能力、摩擦抗阻能力和抗倾覆力矩能力三方面阐述各影响因素对吸盘吸附性能的影响。最后建立有限元仿真模型，利用ANSYS软件对仿生吸盘实体模型进行有限元分析，分析结果表明对鮣鱼吸盘的吸附性能起主要影响作用的是吸盘密封边的密封效果，而该密封效果与材料特性和接触面所受压应力直接相关。

Design and adsorption performance analysis of a bio-inspired suction cup based on the adsorption principle employed by remoras (sukerfish)

In view of the defects of existing bio-inspired suction cups which can generally only be used in dry environments, we decided to explore the adsorption principle employed by remoras (sucherfish). Based on this principle and the negative pressure adsorption principle, we have designed an oval-shaped bio-inspired suction cup. The effects of various factors on the adsorption performance were in terms of the adsorption capacity, frictional resistance capacity and anti-overturning torque capacity. Finally, a finite element simulation model was established. Finite element analysis of a solid model of the bio-inspired suction cup was carried out by using ANSYS software. The results showed that the main effect of the suction cup on the adsorption performance is the sealing of the cup's sealing edge, and the sealing is directly related to the material properties and the compressive stress on the contact surface.
