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 ...

Principal component guided DCGAN for mitigating mode collapse in electromagnetic pulse signal synthesis [PDF]
Scientific ReportsTo mitigate mode collapse in Deep Convolutional Generative Adversarial Networks (DCGANs), this study proposes an innovative deep learning model integrating Principal Component Analysis (PCA)—the PCA-enhanced Deep Convolutional Generative Adversarial ...

Spectral ACMS: A Robust Localized Approximated Component Mode Synthesis Method
SIAM Journal on Numerical Analysis, 2017 We consider finite element methods of multiscale type to approximate solutions for two-dimensional symmetric elliptic partial differential equations with heterogeneous $L^\infty$ coefficients. The methods are of Galerkin type and follow the Variational Multiscale and Localized Orthogonal Decomposition--LOD approaches in the sense that it decouples ...

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.

Modal energy propagation method in coupled systems of rigid and flexible structure
Nihon Kikai Gakkai ronbunshu, 2022 Since the noise generated by mechanical structures affects the merchantability, it is important to predict it at the design stage. Statistical energy analysis (SEA), which solves the energy equilibrium equation between subsystems, is widely used to ...

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).
