Description
Summary:For structural systems that have numerous degrees-of-freedom, or are made up of components designed by separate organizations, the component mode synthesis analysis introduces generalized variables or Ritz coefficients that are neither measurable nor derivable from testing into the final solution set. A technique is presently developed which operates directly on the final component mode synthesis system matrices by eliminating generalized variables and any additional physical degrees-of-freedom not measured during testing, while maintaining the validity of the original system matrices.
