【摘要】： 研究了蚊子与蝉两种刺吸式口器昆虫的口器结构,观察发现刺吸口器的表面存在有明显的非光滑结构。并以刺吸式口器昆虫的口器结构为研究基础开发出波纹形仿生注射器针头。采用正交多项式回归设计编制方案,测出了仿生针头刺入皮肤阻力大小,并得出阻力与因素间的回归方程。同时对比分析了不同速度下针头刺入皮肤阻力的变化情况,最终找出了仿生针头的减阻情况。使用有限元分析软件ANSYS,对仿生针头刺入皮肤过程进行模拟分析,进一步证实了仿生结构的存在能有效减小针头刺入皮肤的阻力。本研究以仿生学为基础,为无痛注射器的研究提供了一个新的方向与理论基础。
[Abstract]:The structure of mouthparts of mosquitoes and cicadas were studied. It was found that there were obvious non-smooth structures on the surface of spurs. Based on the structure of mouthpiece of sucking mouthpiece, a corrugated bionic syringe needle was developed. By using orthogonal polynomial regression design, the resistance of bionic needle into skin was measured, and the regression equation between resistance and factors was obtained. At the same time, the change of needle penetration resistance at different velocities was analyzed, and the drag reduction of biomimetic needle was found out. The finite element analysis software ANSYS, is used to simulate the process of the bionic needle piercing into the skin. It is further proved that the existence of the bionic structure can effectively reduce the resistance of the needle piercing into the skin. Based on bionics, this study provides a new direction and theoretical basis for the study of painless syringes.
