Abstract

Experiencies gained with present modal survey test techniques range from excellent results to unrealistic normal mode parameters. Present experimental modal analysis procedures auffer under the absence of a criterion for optimal exciter placement. In order to increase the reliability and robustness of modern identification methods, a technique for optimal exciter point selection was developed based on combinatorical optimization. Applying three force tuning procedures published in the past and a new method, reliable normal mode parameters of an analytical eleven-degree-of-freedom system and of a real structure could be determined, which verifies the performance of the proposed technique.
