Abstrakt CZ: In the paper the determination of a stress state in any point of a beam element of a mechanical system is presented. The dynamic model consists of rigid bodies (or mass particles), discrete linear-elastic couplings and 1-D continua discretized by finite element method using beam elements. Damping of 1-D continua is considered to be proportionally distributed according to stiffness. The excitation of the system is a polyharmonic one, the analysis is performed for the steady state. The analysis is applied to the dynamic model of the WWER 1000 nuclear reactor in NPP Temelin. The model is excited by pressure pulsations generated by various combinations of working cirkulation pumps in cooling loops.
