[Stress analysis of artificial bionic knee joint based on UG6.0 NX NASTRAN].

This article introduces the basic principles of finite element analysis in biomechanics, focusing on the basic principles of a variety of finite element analysis software, and their respective characteristics. In addition, it also de scribes the basic stress analysis of UGNX6.0 NASTRAN analysis for artificial knee process, i. e. the choice of the type, material definition, the set of constants, finite element mesh division and the finite element results of the analysis. Finite element analysis and evaluation of the design of personalized artificial knee were carried out, so that the rationality of the geometric design of the structure of the experimental design of artificial knee has been verified.
