Abstract A self-calibration method and damping ratio calibration calculation step of seismic accelerometer in nuclear power plant are introduced. The structural principle of seismic accelerometer is analyzed, and the transfer function of step signal response is given. Based on this, the self-calibration calculation formula and specific calculation process for damping ratio are provided. The experimental verification of seismic accelerometer prototypes show that the calculation results are consistent with the damping ratio index provided by the equipment manufacturer, and the calculation method has practical value in nuclear power plant engineering applications.
