Substructuring and Component Mode Synthesis [PDF]
Shock and Vibration, 1997 Substructuring and component mode synthesis (CMS), is a very popular method of model reduction for large structural dynamics problems. Starting from the pioneering works on this technique in the early 1960s, many researchers have studied and used this ...

Model Updating of Complex Structures Using the Combination of Component Mode Synthesis and Kriging Predictor [PDF]
The Scientific World Journal, 2014 Updating the structural model of complex structures is time-consuming due to the large size of the finite element model (FEM). Using conventional methods for these cases is computationally expensive or even impossible.

Mode selection for component mode synthesis with guaranteed assembly accuracy
Journal of Sound and VibrationIn this work, a modular approach is introduced to select the most important eigenmodes for each component of a composed structural dynamics system to obtain the required accuracy of the reduced-order assembly model. To enable the use of models of complex (structural) dynamical systems in engineering practice, e.g., in a design, optimization and/or ...

Modal Analysis of Complex Structures via a Sub-Structuring Approach [PDF]
International Journal of Advanced Design and Manufacturing Technology, 2021 In this paper, the problems arising from determining the modal properties of large and complex structures are investigated. For this purpose, the free interface component mode synthesis method has been used. In the following, Singular-Value Decomposition

Stochastic Component Mode Synthesis [PDF]
44th AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics, and Materials Conference, 2003 In this paper, a stochastic component mode synthesis method is developed for the dynamic analysis of large-scale structures with parameter uncertainties. The main idea is to represent each component displacement using a subspace spanned by a set of stochastic basis vectors in the same fashion as in stochastic reduced basis methods [1, 2]. These vectors

Characteristic constraint modes for component mode synthesis [PDF]
AIAA Journal, 1999 Abstract In this paper, a technique is presented for improving the efficiency of the Craig-Bampton method of Component Mode Synthesis (CMS). An eigenanalysis is performed on the partitions of the CMS mass and stiffness matrices that correspond to the so-called constraint modes.

Improved Craig–Bampton Method Implemented into Durability Analysis of Flexible Multibody Systems
Actuators, 2023 The Craig–Bampton method is frequently applied in most commercial multibody dynamic software. Nevertheless, the Craig–Bampton modes only represent the free-free modes in flexible multibody systems.

A Parallel Approach of the Enhanced Craig–Bampton Method
Mathematics, 2021 The enhanced Craig–Bampton (ECB) method is a novel extension of the original Craig–Bampton (CB) method, which has been widely used for component mode synthesis (CMS).
