Fundamental Study on Vibration Characteristics of Mechanical Structure at High Frequency Band : 2nd Report, Experimental Result

At present, mechanical structures in the nuclear power plants such as equipments or piping that have high natural frequency are basically assumed to be rigid body, and are designed by applying static method. In the meantime it is also" expected that the rupture of the equipment and the piping that has high natural frequency is caused cumulative fatigue damage. Therefore the investigations into the vibration characteristics and the rupture properties of the mechanical structures at high frequency band are important. In the 1st report of this study, vibration characteristics at high frequency band are investigated by numerical analysis and energy balance. In this 2nd report, experiment on the model that has natural frequency of high band is reported.
