Raising accuracy of dynamical synthesis of subconstructions in the method of rigid boundaries for discrete models

Description of dynamical synthesis for the subconstructions represented by discrete models (in particular, by finite element ones) is performed with the use of correcting series in the rigid boundary variant. The algorithm for constructing the matrix of the subconstruction dynamic rigidities is worked out. The case of conservative system is considered, generalization is performed as applied to proportional damping. The proposed method accuracy and efficiency research is carried out on the particular examples.
