Strategic Study of CAE 2001, Volume 3, Issue 10, Pages 59-63
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.

To predict more precisely the frequency of force-balanced micro accelerometer with different biasvoltages, the effects of bias voltages on error sensitivity of frequency is studied.The resonance frequency of accelerometer under closed loop control is derived according to its operationExperimental results indicate that the relative errors between test data and theory data are less thansensitivity with designed parameters of structure, circuit and process error can be used to predict the frequency
