与精密抛光气缸套表面相比，爬行动物蜕皮中的承载摩擦参数的表征
Characterization of load bearing metrological parameters in reptilian exuviae in comparison to precision finished cylinder liner surfaces
摘要：
精确功能表面的设计对于许多未来应用至关重要。在技术领域中，积累的建造这种表面的经验是不够的。自然界提供了许多值得研究和采用的动态表面的例子，至少作为一个概念，在人类工程学中。在这项工作中，我们探讨蛇表面的腹侧皮肤的承重功能。我们研究了两种主要由直线运动的蛇的结构。它们是蟒蛇科（Python regius）和蝰蛇科（Vipridae）。为此，我们专注于腹侧皮肤表面的承载特性（即Rk族参数）。因此，我们在爬行动物表面和两组技术数据之间进行了详细的比较。第一组与实际的商用气缸套有关，而第二组是几个商用气缸套制造商推荐的表面光洁度值的总结。结果突出了两种类型的表面之间的一些相似之处。特别是，我们表明，有一个惊人的对应关系的纹理工程的感觉在两个表面（虽然他们的建设沿着完全不同的路径演变）。我们还表明，爬行动物的表面表现出高度的专业化与栖息地的限制耐磨性和粘合剂的影响。
英文摘要：
Design of precise functional surfaces is essential for many future applications. In the technological realm, the accumulated experience with the construction of such surfaces is not sufficient. Nature provides many examples of dynamic surfaces worthy of study and adoption, at least as a concept, within human engineering. In this work, we probe load-bearing features of the ventral skin of snake surfaces. We examine the structure of two snake species that mainly move by rectilinear locomotion. These are Python regius (pythonidae) and Bittis gabonica (Vipridae). To this end, we focus on the load bearing characteristics of the ventral skin surface (i.e. the Rk family of parameters). Therefore, we draw detailed comparison between the reptilian surfaces and two sets of technological data. The first set pertains to an actual commercial cylinder liner, whereas, the second set is a summary of recommended surface finish metrological values for several commercial cylinder liner manufacturers. The results highlight several similarities between the two types of surfaces. In particular, we show that there is a striking correspondence between the sense of texture engineering within both surfaces (although that their construction evolved along entirely different paths). We also show that reptilian surfaces manifest a high degree of specialization with respect to habitat constraints on wear resistance and adhesive effects.
