Abstract

Based on the observed micromorphology of the Sinogastromyzon szechuanensis, a groove morphology was designed on the sucker working surface. The length, width, and number of the grooved morphology were selected as the design factors for the bionic morphology. The bionic and standard sucker was fabricated using the mold method, and the sucker adsorption performance was tested. Compared to the standard sucker adsorption force on the substrate (33.20 N), the bio-inspired sucker adsorption force could increase by a maximum of 71.22 %. The change law of the adsorption force was the same as the change law of negative pressure holding time. The bionic sucker could form multiple micro-sealing cavities from the groove morphology while forming a normal sealing cavity with the substrate. The bionic sucker adsorption force was greater than that of the standard sucker. As the length and width of the groove increased, the micro-sealing cavity formed by the groove shape made it difficult to form micro-suckers during the adsorption process, and the adsorption force was affected. With the increase in the number of grooves, the number of micro-suckers formed between the morphology and the substrate during the adsorption process could increase, and the adsorption force was increased.

以川菜为原料，设计高吸附性能的仿生吸盘

根据对四川海螺的微观形貌观察，设计了吸盘工作面沟槽形态。选择沟槽形态的长度、宽度和数量作为仿生形态的设计因素。采用模法制备了仿生吸盘和标准吸盘，并对吸盘的吸附性能进行了测试。与标准吸盘吸附力（33.20 N）相比，仿生吸盘吸附力最大可提高71.22 %。吸附力的变化规律与负压保持时间的变化规律相同。仿生吸盘在与衬底形成正常密封腔的同时，可从凹槽形态形成多个微密封腔。仿生吸盘吸附力大于标准吸盘吸附力。随着凹槽长度和宽度的增加，凹槽形状形成的微密封腔使得吸附过程中难以形成微吸盘，从而影响吸附力。随着凹槽数量的增加，吸附过程中形貌与基体之间形成的微吸盘数量会增加，吸附力也会增大。
