Název v původním jazyce

Analytical and experimental loose part impact mass and energy evaluation

Popis výsledku v původním jazyce

Loose Part Monitoring System is wide spread in the primary coolant system in nuclear power plants. One part of this system should be the mass and energy estimation of detected loose parts. This system is based on the measurement of the vibrations excitedby the impact. Very useful indicators are contact time, forces and spectrum of vibrations. In this paper, these indicators are analyzed with use of experimental data obtained under laboratory conditions. The impact objects were steel spheres of variousmass, impact velocities and angles. The target object was a steel desk. Signals were measured by piezoelectric accelerometers and were analyzed in time, frequency and in time-frequency domain. The situation was solved analytically and simultaneously by FEM and both methods were compared with experiments.
