SUPERELEMENT FORMULATION OF THE METHOD OF FREQUENCY AND DYNAMIC CONDENSATION

UDK: 624.042

Romashkin V. N.

Disadvantages of classical method of the frequency and dynamic condensation (FDC) for the equations of finite element method are revealed. The results of the researches on application of the method of substructures (superelements) to increase the efficiency of the FDC method are provided. Single-level and multilevel schemes of division into substructures are considered in the article. The assessment of accuracy of offered options of the FDC method when calculating one-dimensional and two-dimensional beam systems on free fluctuations is given.
