鲨鱼体表的盾鳞沟槽结构具有显著的减阻效果。鲨鱼仿生沟槽结构的应用涉及航空、舰艇、汽车、管路运输、风力发电等领域。鲨鱼皮沟槽结构的仿生制造主要有两个途径,即沟槽结构形式与鲨鱼盾鳞仿真结构形式。文章针对沟槽结构的微槽滚压、金刚石多轮廓磨削、飞秒激光烧蚀等制造技术,及鲨鱼盾鳞仿真结构的微压印法、固化法、微电铸法、微纳米滚压法、软刻技术等进行了综述,并对鲨鱼皮仿生结构制造技术进行了展望。
Abstract：The riblet structure of shark skin is proved to significantly effect drag reduction.The bionic riblet structure is widely applied in industry,such as aviation,naval vessels,automotives,pipe transportation and wind power generation.The fabrication of the bionic riblet structures focuses on two styles:simplified riblet structure and shark placoid scales directly replication.As to the former style,the typical technologies of micro-riblet rolling,diamond profile grinding,femtosecond laser ablation are reviewed.And the technologies of micro-thermal pressing,solidification,micro-casting,mirco/nano-rolling and soft lithography are also reviewed for the latter style.Finally,the suggestions on the riblet structure fabricating are presented.
