The invention discloses a flexible skin for an underwater navigation body based on active deformation resistance reduction and a design method of the flexible skin, and relates to the technical field of manufacturing, and the method comprises the steps that the flexible skin for the underwater navigation body based on active deformation resistance reduction is provided, and the flexible skin is attached to the outer surface of the underwater navigation body. The flexible skin comprises a magnetic substrate layer and a flexible insulating material layer which are sequentially stacked together. A plurality of parallel induction filaments are arranged in the flexible insulating material layer, and the length direction of the induction filaments is in the circumferential direction of the underwater navigation body. The magnetic substrate layer is electrified with alternating current and generates magnetic force with changing directions, and the induction filaments drive the outer surface of the flexible insulating substance layer to fluctuate and deform under the action of the magnetic force. According to the design method of the flexible skin for the underwater navigation body, design parameters of the flexible skin are determined through viscous flow numerical simulation. Friction resistance of the underwater navigation body is effectively reduced by means of fluctuation deformation of the outer surface of the flexible insulating material layer.

    本申请公开了一种基于主动变形减阻的水中航行体用柔性表皮及其设计方法,涉及制造技术领域,该方法包括:提供一种基于主动变形减阻的水中航行体用柔性表皮,所述柔性表皮贴覆在水中航行体的外表面。柔性表皮包括依次层叠在一起的磁性基底层和柔性绝缘物质层。柔性绝缘物质层内部设有多根平行的感应纤丝,感应纤丝的长度方向沿着水中航行体的周向。磁性基底层通有交变电流并产生方向变化的磁力,感应纤丝在磁力作用下带动柔性绝缘物质层外表面进行波动变形。提供了一种水中航行体用柔性表皮的设计方法,通过粘流数值模拟确定柔性表皮的设计参数。利用柔性绝缘物质层外表面的波动变形,有效减小水中航行体的摩擦阻力。
