TEST-ANALYSIS CORRELATION USING DESIGN SENSITIVITY AND OPTIMIZATION-DOES IT WORK?

Mathematical models of structures are validated by adjusting them to match the results of static and dynamic tests. Several automated methods have been developed to aid in the test-analysis correlation process. A recent method uses design sensitivity and optimization methods to directly adjust the Finite element model. The strengths and weaknesses of this method are demonstrated by the test-analysis correlation results from several modal surveys.
