Abstract

Some pipe lines of a nuclear power plant exists serious vibration that seriously affected the normal production safety. By the spectral analysis of measured time domain signal, the main vibration frequency of the pipe lines was obtained. The model analysis was processed with pipe stress analysis software CAESAR II. The natural frequency was found. According to the causes of pipe lines vibration, the simple way of eliminating the vibration was given, and the results showed that the vibrating method effect is effective.
