Hybrid Reduced Model of Continuous System

Abstract

The paper introduces an alternative method of modelling and modal reduction of continuous systems. Presented method is a hybrid one. It combines the advantages of modal decomposition method and the rigid finite element method. In the proposed method continuous structure is divided into one-dimensional continuous elements. For each 1D element modal decomposition and reduction is applied. Interactions between substructures are described by lumping techniques. Presented method enables to obtain reduced, low order modal model of considered system. The proposed approach is illustrated by selected examples
