Kurzfassung
This paper introduces two novel Component Mode Synthesis (CMS) techniques. It begins with an overview of existing CMS approaches. A dual assembly method using fixed-interface modes is formulated based on the Craig-Bampton approach and a further condensation of the interface degrees-of-freedom (DOF) as in MacNeal’s Method is carried out. Then, a dual assembly method employing free-interface modes is derived by integrating the principles of the Dual Craig-Bampton Method with simplifications from MacNeal’s Method. Finally, the proposed methods are evaluated against established techniques through two examples spanning structural and acoustic models. This comparison is conducted in both the modal and frequency domains, providing a detailed analysis of their performance and computational efficiency.
