Diagnostics of vibrations in induction motor-pump system used for reactor core cooling system

Analysis and diagnostics of vibration in industrial systems play a significant rule to prevent severe damages. This paper proposes a non-linear model to simulate the torsional vibration in the reactor core cooling system. Simulation results of an operating reactor core cooling system set with the actual parameters are presented to validate the accuracy and reliability of the proposed analytical method. Also the translational vibration measurements on the reactor core cooling system are introduced.
