Abstract
In this paper, focusing on practical engineering application of Finite Element Model (FEM) updating technology, the authors discuss some key problems and bring forward their own points of view. This paper explains the basic thought and numerical method of a FEM updating approach that has achieved the level of practical engineering application. This paper also presents the difficulties in the practical engineering application of Finite Element Model (FEM) updating technology, and indicates the ways by which those difficulties can be solved.
