  • The Component Mode Synthesis (CMS) method is a Raleigh-Ritz technique, which allows structural models to be reduced in size and coupled with other analytical or experimental components. The CMS transformation uses combinations of static and dynamic trial vectors. Static trial vectors (constraint modes) for all component interface degrees of freedom (DOF) and externally loaded DOF need to be included in the CMS transformation to produce a statically complete CMS transformation. This requirement for aerospace models with surface pressure loads would be restrictive. This study will investigate techniques for producing a statically complete solution using a CMS method, which has amore » statically incomplete set of constraint modes. The study will also investigate the additional problems involved with the multi-level CMS. The study will be conducted by modifying the transient and frequency response solution sequences of NASTRAN.« less
  • Component mode synthesis methods for computing the natural frequencies of elastic supports (steel-elastomer composite structures) are presented. Inside the framework of these methods, a structure is subdivided into substructures which are analyzed independently. Thanks to coupling modes the substructure mode shapes are then assembled to give eigenmodes of the global structure. The coupling modes are defined as the harmonic lifting of the eigenmodes of suitable interface operators. By the use of domain decomposition techniques, the interface operators are not explicitly built. In consequence the dynamical substructuring methods developed here are especially well adapted for parallel computing.
