Modal Synthesis Method for General Dynamic Systems
Journal of Engineering Mechanics, 1992A modal synthesis method is presented to calculate the lower eigenproperties of a general dynamic system divided into subsystems. The left and right eigenproperties of the subsystems associated with their equations of motion expressed in the state form are used.

An eigenvector‐based iterative procedure for the free‐interface component modal synthesis method
International Journal for Numerical Methods in Engineering, 2018SummaryA novel eigenvector‐based iteration procedure is developed for the free‐interface component modal synthesis (CMS) method. To derive the iteration formula, Kron's substructuring is employed to distribute the computations of subspace iteration, and the free‐interface component modes are chosen as the initial guess.

A dynamic transformation method for modal synthesis
14th Structures, Structural Dynamics, and Materials Conference, 1973This paper presents a condensation method for large discrete parameter vibration analysis of complex structures that greatly reduces truncation errors and provides accurate definition of modes in a selected frequency range. A dynamic transformation is obtained from the partitioned equations of motion that relates modes not explicity in the condensed ...

A Survey of Modal Synthesis Methods
SAE Technical Paper Series, 1971<div class="htmlview paragraph">Several modal synthesis procedures for the dynamic analysis of large composite structural systems are surveyed. The matrix formulation of the free-free modal synthesis procedures is presented. Also given are schematic flow charts of the analysis procedure used in three prominent methods.

METHOD OF MODAL SYNTHESIS IN THE DYNAMICS OF A DEFORMABLE SPATIAL STRUCTURE
Far East Journal of Dynamical Systems, 2018Summary: The modal analysis of a rotating elastic space vehicle composed of a central rigid body connected to two solar arrays is the subject of this investigation. The global modes differential equations of the whole mechanical system are defined by means of Hamilton variational principle.

A Minimization Method for Treating Convergence in Modal Synthesis
AIAA Journal, 1974The problem of convergence in modal synthesis is solved by a minimization approach. Substructure modes corresponding to fixed-interface boundaries are considered. The Rayleigh quotient of the structure is defined in a coordinate space which includes the initial selection of substructure modes augmented by some of the unused modes.

Transient Response by Component Modal Synthesis Method
Journal of Vibration and Acoustics, 1990A method for determining the transient responses of a system is introduced. This method is an extension of the component modal synthesis technique. The transient responses of the system are computed based on the substructure modal parameters, the geometric compatibility, and the force equilibrium equations between substructures.

Improved fixed interface method for modal synthesis
AIAA Journal, 1992An improved technique for synthesizing the modes obtained with fixed interface coordinates is proposed. The reduction in the size of a substructure model is achieved through a higher order mode superposition approach. For the first time, an analytical rationale for the popular Craig-Bampton-Hurty method is presented. It is shown that the Craig- Bampton-

Modal Methods in Optimal Control Synthesis
1980Efficient algorithms for solving linear smoother-follower problems with quadratic criteria are presented. For time-invariant systems, the algorithm consists of one backward integration of a linear vector equation and one forward integration of another linear vector equation.
