- Abstract:
- Both the numerical analysis and seismic qualification test of the response characteristics of the back-up panel(BUP)in the control room of the nuclear power plant subjected to the earthquake are carried out.The response-spectrum analysis shows that the maximum Mises stress of the BUP is 91.89 MPa,less than the maximum yield limit stress of structural material.Thus,the BUP has ideal aseismic performance.The time-history analysis shows that with the increase of the structure’s height,the maximum response of the structure gradually increases,and the vibration amplitude in the lateral direction is the most obvious.Further,time-frequency analysis of the vibration signals in the installation area of the display screen is carried out,revealing that the peak energy in three directions at the same point is mainly located in 2-3 Hz,but the time interval is deferent.The lateral peak energy is about 2 times of the longitudinal and vertical ones.The seismic test and analysis show that with the increase of the height,the amplitude of the vibration acceleration increases gradually,and the vibration signal amplification in the lateral direction is the most significant.Therefore,inhibiting the lateral movement of the BUP is the key to improving the aseismic performance of the structure.After the seismic test,the overall structure of the BUP has no visible deformation or rupture,and the connectors do not loosen or fall off,suggesting that the BUP has passed the seismic test.
