Notes:
The dynamic condensation methods make it possible to reduce the size of large matrix systems occurring in mechanics in order to obtain an accurate description of behaviours. In the first instance, we have reviewed the methods currently available. Then, we have presented the latest improvements which have been introduced with respect to the ‘Free Mode’ method. The use of an innovative technique for the determination of residual flexibility matrices, the consideration of an additional term in the expansions and a shift in frequencies have made this method particularly accurate and worthy of interest. In the present paper, we have presented an example which, however simple, has the merit of highlighting the qualities of the proposed method by drawing comparisons with the results achieved through the application of other methods.
