The invention discloses an equal-diameter rotary body with an underwater resistance reduction function and a vein-imitating composite microstructure thereof, the equal-diameter rotary body is used for being arranged on the outer surface of an equal-diameter rotary base body, and the equal-diameter rotary body comprises a plurality of first main groove bodies, a plurality of second main groove bodies and a plurality of second main groove bodies, a plurality of first branch grooves communicated with the first main groove body are formed in the first side of each first main groove body, a plurality of second branch grooves communicated with the first main groove body are formed in the second side of each main groove body, and the first branch grooves and the second branch grooves of each first main groove body face the same direction; the first branch grooves of each first main groove body are communicated with the second branch grooves of one adjacent first main groove body in a one-to-one correspondence mode, and the second branch grooves of each second main groove body are communicated with the first branch grooves of the other adjacent first main groove body in a one-to-one correspondence mode. Bionic resistance reduction and the V-shaped grooves are combined to form a bionic non-smooth resistance reduction structure, namely a vein-imitating composite microstructure, on the surface of a smooth equal-diameter rotary body, and resistance reduction can be effectively carried out.

    本发明公开了一种具有水下减阻功能的等径回转体及其仿叶脉复合微结构,用于设置在等径回转基体的外表面上,包括:多个第一主槽体,多个第一主槽体沿等径回转体的轴向延伸;每个第一主槽体的第一侧均设有多个与第一主槽体连通的第一支槽,每个主槽体的第二侧均设有多个与第一主槽体连通的第二支槽,每个第一主槽体的第一支槽和第二支槽的朝向均相同,且每个第一主槽体的第一支槽与相邻的一个第一主槽体的多个第二支槽一一对应地连通,每个第二主槽体的第二支槽与相邻的另一个第一主槽体的第一支槽一一对应地连通。本发明将仿生减阻与V型沟槽结合用于光滑等径回转体表面形成仿生非光滑减阻结构—仿叶脉复合微结构,能够有效进行减阻。
