Abstract EN
This paper presents an innovative approach to model validation for a structure with significant parameter variations.
Model uncertainty of the structural dynamics is quantified with the use of a singular value decomposition technique to extract the principal components of parameter change, and an interval model is generated to represent the system with parameter uncertainty.
The coordinate vector, corresponding to the identified principal directions, of the validation system is computed.
The coordinate distance between the validation system and the identified interval model is used as a metric for model validation.
A beam structure with an attached subsystem, which has significant parameter uncertainty, is used to demonstrate the proposed approach.
