Seismic reliability analysis of vertical pumps.

抄録

This paper deals with the evaluation of the cumulative damage of a vertical pump's rotor shaft subjected to earthquake excitation. The equation of motion is derived, and the behavior of the rotor is calculated. The torsional moment due to the collision is calculated and used to evaluate the cumulative damage of the shaft. From this analysis, it is clear that the shaft of the vertical pump for a nuclear power plant has enough reliability to withstand earthquake excitation.
