摘要：Structural size optimization of a device for external bone fxation within a formed iterative hybrid optimizationalgorithm was presented in this paper. The optimization algorithm was in interaction with the algorithms for generative design and FEM analysis and completely integrated within CATIA CAD/CAM/CAE system. The initialmodel, representing the current design of the bone external fxation device Sarafx, was previously verifed byexperimental testing. The formed hybrid optimization algorithm was created as an integration of the global (SAmethod) and local (CG method) algorithm. The constraints of the optimization model are the clinical limitationsof the interfragmentary displacements and the material strength. The optimized design has less weight, greaterrigidity and less transverse interfragmentary displacements at the point of fracture compared to the current design.
