Mode selection for component mode synthesis with guaranteed assembly accuracy [PDF]

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 ...

Component Mode Synthesis Using Nonlinear Normal Modes

Nonlinear Dynamics, 2003
This paper describes a methodology for developing reduced-order dynamic models of nonlinear structural systems that are composed of an assembly of component structures. The approach is a nonlinear extension of the fixed-interface component mode synthesis technique developed for linear structures by Hurty and modified by Craig and Bampton. Specifically,

Component mode synthesis for nonclassically damped systems

AIAA Journal, 1996
Summary: A formulation of a component mode synthesis (CMS) free-interface method is presented and tested on different examples of unforced nonclassically damped systems with symmetric mass, stiffness, and damping matrices. Excellent agreement of the results with the exact ones (unsubdivided systems) is obtained.

Evaluating Mode Selection Methods for Component Mode Synthesis

AIAA Journal, 2016
Component mode synthesis is a popular reduced-order modeling technique with a substructuring strategy in structural dynamics. The ideal goal of component mode synthesis is to construct compact reduced models with adequate accuracy for specific intended applications. In this paper, five a priori mode selection methods plus an a posteriori mode selection

Component mode synthesis techniques for finite element model updating

Computers and Structures, 2013
Deterministic and Bayesian finite element (FE) model updating techniques are computationally very demanding operations due to the large number of FE model re-analyses required. Component mode synthesis techniques are proposed to carry out the re-analyses
