Methods of Component Mode Synthesis
The Shock and Vibration Digest, 1977A generalized substructure coupling, or component mode synthesis, procedure is described. Specific methods, applications, and such special topics as damping and experimental verification are surveyed.

A model-updating approach based on the component mode synthesis method and perturbation analysis
Journal of Sound and Vibration, 2018A model-updating approach based on an improved free-interface component mode synthesis method is proposed. First, the equivalent higher-order matrix of the system is developed using a set of linearly independent vectors to capture the effects of the ...

The component mode synthesis (CMS) or component modal synthesis [Hintz 75] or modal coupling technique [Maia 97] is used when components (substructures) are described by the mode displacement method (MDM) and coupled together (synthesis) via the common boundaries {x b } in order to perform a dynamic analysis, e.g.

Adaptive component mode synthesis in linear elasticity
International Journal for Numerical Methods in Engineering, 2010AbstractComponent mode synthesis (CMS) is a classical method for the reduction of large‐scale finite element models in linear elasticity. In this paper we develop a methodology for adaptive refinement of CMS models. The methodology is based on a posteriori error estimates that determine to what degree each CMS subspace influence the error in the ...

Component-Mode-Synthesis-Based Method for Structural Synthesis
1995In many engineering applications, selection of subcomponents for assembly into a useful structure is a more important design decision than modification of the detailed dimensions of individual subcomponent. Examples in the automobile industry include selection of strength members of the roof of a van to enhance buckling resistance or placement of ...

Improved component mode synthesis and variants
Multibody System Dynamics, 2012This survey focuses on the two known model order reduction schemes being widely integrated in various commercial finite element packages, namely, the static and dynamic condensation methods. The advantages as well as the corresponding drawbacks have been extensively analyzed in several papers throughout the last decades.

Component Mode Synthesis of Large Rotor Systems
Journal of Engineering for Power, 1982A scheme is presented for calculating the vibrations of large multi-component flexible rotor systems based on the component mode synthesis method. It is shown that, by a modal expansion of the elastic interconnecting elements, the system modal equation can be conveniently constructed from the undamped eigen representations of the component subsystems ...

Component mode synthesis for damped structures
AIAA Journal, 1987This paper formulates and investigates component mode synthesis methods for structures with the nonproportional symmetric damping matrix. The use of three different types of modes is discussed: complex free-free, cantilever, and hybrid. For ease of computation, the reduction transformation equations are expressed in real numbers with partitions from ...

Spurious results of the component mode synthesis
Computers & Structures, 1973Abstract The natural frequencies and mode shapes of a bentbeam in flexure-torsion oscillation are examined using the modal synthesis technique. The problem involves six boundary constraint conditions and the effect of ignoring a number of these conditions are examined. The choice of generalized coordinates offer other variations in the problem.
