A modal coupling procedure to improve residual modal effects based on experimentally generated data
This paper deals with dynamic analyses of structures using the component mode synthesis method. In this method, the original structure is decomposed into simpler and smaller substructures, and the modal properties of the resulting substructures are first evaluated independently. In order to avoid inaccuracies normally associated with the modal coupling results, we proposed a modified method to assess the effect of neglecting the higher frequency modes during the regenerating process. The proposed modified method offers a more accurate way of analysing structures using data from the substructures, and has a considerable impact on the accuracy of dynamic design of structures.
