摘　　要：介绍了仿生工程学研究领域的重大发现,即自然界中,无论是陆地、海洋还是天空中的生物,为适应不同的生活环境需要进化而成的表面,都是非光滑表面,该非光滑表面具有减粘、脱附、减阻的特性。实践证明,有规律的非光滑表面还具有耐磨特性,用在发动机活塞表面和轧辊表面均能大幅度提高使用寿命。将仿生非光滑特性应用到金刚石钻头的设计上,研制出了JBD-75S仿生非光滑绳索取心金刚石钻头。现场试验证明,在同样的加工工艺和使用条件下,有规律的仿生非光滑表面金刚石钻头比普通金刚石钻头机械钻速提高47%-83%,钻头寿命提高2.43-2.61倍。A remarkable discovery in bionics engineering is introduced in this paper. Namely, all creatures in nature living on land or in ocean have non-smooth skins evolved naturally in order to accustom to various living environments. Their non-smooth skins are helpful to decrease viscosity, to remove adhesion and to reduce drag, etc. In addition, regular non-smooth skin is abrasion-proof, and can be used on the surface of generator piston and roller to improve using time. A diamond core bit JBD-75S was developed using this bionics theory. The field tests demonstrate that diamond bits with regular non-smooth bionics surface improve the drilling speed up to 47%-83% and the bit life 2.43-2.61 times compared with conventional diamond bit manufactured at the same conditions.
