An exact component mode synthesis approach
Earthquake Engineering & Structural Dynamics, 1988AbstractThe paper presents a method for synthesizing the modal properties of substructures to obtain the exact modal properties of a combined structure. Unlike the currently available modal synthesis approaches, the proposed approach does not require the solution of any transformed eigenvalue problem of the combined structure by conventional means. The

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.

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.

Convergence improvement for component mode synthesis
AIAA Journal, 1992Model order reduction by component mode synthesis relies on the truncation of high-frequenc y component modes. Such truncations inevitably lead to approximate solutions for the system frequencies and mode shapes. A technique is proposed to improve the accuracy of the computed system modal content.

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 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 ...

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 ...

Complex component mode synthesis for damped systems
Journal of Sound and Vibration, 1995Abstract A general free-interface complex component mode synthesis (CMS), which uses truncated component complex modes, complemented with residual flexibility and inertia-relief modes, has been developed and allows assembly of a damped multi-component system with rigid and/or flexible interfaces.
