The component mode synthesis (CMS) technique has been widely used in engineering for its efficiency in dynamic analyses. The principle of CMS with fixed interfaces is introduced, the detail steps in calculation are summed up, and the flow chart of algorithm is also given. The dynamic properties of elastic tube bundles are investigated with the application of CMS. The effect of numbers of nominal modes and constrained modes on the results’ accuracy is also studied. The results show that this method is very effective when deal with the structure with complex shapes and complicated boundary conditions.
