Component mode synthesis(CMS) method can be divided into Free, Fixed and Hybrid interface method according to each component's contact conditions. In this thesis, major mode synthesis methods were reviewed and their accuracies were examined by comparing the calculated eigenvalues with those from full FE mode.
Also, CMS is expanded into the coupling between FE and experimental model. Since the experimental data seldom have slope information, the slope information at interface point are prepared by curve-fitting the measured values. A simple beam and a plate structure are tested to show the effectiveness of the above method, and found that it can improve the synthesis accuracy especially in low modes.
