description The invention relates to a method for designing a porous structure on the surface of an external fixation support. The method comprises the steps that S10, finite element models of the external fixation support, steel nails and autogenous bones are established; s20, simulating a real stress condition to perform simulation analysis on the finite element model; s30, topological optimization is conducted on the external fixing support according to the simulation analysis result; and S40, carrying out surface porous design on the external fixing bracket according to a topological optimization result. According to the design method for the surface porous structure of the external fixation support, mechanical finite element analysis is taken as a theoretical basis, and the surface porous structure is constructed through topological optimization, so that the minimum size of the external fixation support is ensured, the air permeability and portability of the external fixation support are improved, a patient can wear
