有限元模型修正方法的改进
Improved Methods for Finite Element Model Updating Problems
摘要
Abstract
This paper is concerned the finite element model updating problems. We present two new methods by using the least squares approach, which improve the results proposed by Kuo Y C, Lin W W and Xu S F. Without increasing the computational cost, these new methods can simplify the computation process, The numerical experiments show the effectiveness of the algorithms.关键词
