概要

論文の詳細を見る
An approach is presented for the identification of modal parameters in frequency domain in an experimental modal analysis with multiple frequency response functions, using the non-linear least squares method and the optimization method. Computation time is reduced, and, stability and accuracy of results are improved compared with thone of conventional approach, when input bata are contaminated with errors. Validity and usefulness of presented approach are verified experimentally with an iron plate.
