| Abstract: | This paper deals with the theory and application of the experimental modal analysis by means of the impulse hammer excitation.Using this method, the experimental analysis of the dynamic behaviour of a quadrate steel plate is carried out, and modal parameters of the plate are obtained satisfactorily. Some problems are also presented which deserve further investigation. |
