WebBased on the new method, the kinematics of contact surfaces are first described in terms of relative displacements between contact node pairs, afterwards the Craig-Bampton Component Mode... WebSep 12, 2024 · In this paper, Craig–Bampton method is adopted to evaluate the performance of model reduction. The structural system is considered to be an assembly of sub-systems and these sub-systems are called component modes. Vibration mode for each component is determined separately and is used to get overall dynamics of the whole …
