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.

Dynamic analysis of large structures with uncertain parameters based on coupling component mode synthesis and perturbation method

Ain Shams Engineering Journal, 2016
This paper presents a methodological approach to compute the stochastic eigenmodes of large FE models with parameter uncertainties based on coupling of second order perturbation method and component mode synthesis methods.

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 ...

Mode selection for component mode synthesis with guaranteed assembly accuracy

Journal of Sound and Vibration
In 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 ...

Principal component guided DCGAN for mitigating mode collapse in electromagnetic pulse signal synthesis [PDF]

Scientific Reports
To 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 ...

A massless boundary component mode synthesis method for elastodynamic contact problems [PDF]

Computers & structures, 2021
We propose to combine the ideas of mass redistribution and component mode synthesis. More specifically, we employ the MacNeal method, which readily leads to a singular mass matrix, and an accordingly modified version of the Craig-Bampton method.

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

An artificial spring component mode synthesis method for built-up structures

International Journal of Mechanical Sciences, 2022
12 In this paper, we develop a component mode synthesis method that relies on artificial springs to connect 13 the subsystems of a built-up structure. The modal behaviour of the subsystems can be computed using 14 different approaches, from analytical to

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
