Computational model updating of large scale finite element models

In this paper a model validation strategy is presented that integrates computational model updating techniques. A special in-house software package is utilized that makes use of a wide range of the analysis capabilities of a commercial Finite Element solver, especially the eigenvalue and the sensitivity module. The software package thus allows for efficient computational model updating of large scale Finite Element models. At first the basic theory is summarized. Then the model validation strategy is explained. Finally an application to an automotive transmission will underline the effectiveness of the procedure.
