ANALYSIS OF FORCED VIBRATIONS OF FRAMEWORKS BY FINITE ELEMENT METHOD USING DYNAMIC FINITE ELEMENT.
Abstract and keywords
Abstract (English):
The analysis of forced vibrations of frameworks using finite element method is considered. The dynamic finite element, the base functions of which represent exact dynamic shapes of structural elements, is used for system discretization. The assessment of errors as a result of classic FEM application is given. The efficiency of application of dynamic finite element for analysis of forced vibrations and dynamic stress-deformed state of structures is shown.

Keywords:
finite element method, dynamic finite element, forced vibrations, frameworks, harmonic force, resonance, amplitude-frequency characteristics, stress-deformed state.
