Abstract:
Finite element method (FEM)is a calculating method for stress and strain analysis in the field of mechanical engineering.FEM has already been used in the design of medical apparatus,especially of the fixer for fracture treatment.The external fixer taken as an example,the anti-compression,anti-blending and anti-torsion characteristics of a certain type of external fixer are analyzed using FEM.This paper shows that by using FEM,the mechanical property of medical apparatus can be revealed at the designing stage.The strength and rigidity weak pocket can be found,and thus the improvement and optimization of medical apparatus can be made.
