Background

At present, the instrument control equipment of the nuclear power plant has hundreds of types, and different products have different requirements on the tool clamp in the identification test process. When the anti-seismic equipment carries out anti-seismic test, actual installation conditions need to be simulated, including installation direction, installation mode etc. and it is ensured that simulation experiment conditions coincide with actual vibrations environment. The earthquake-resistant equipment to be identified is required to be connected and fixed between the earthquake table and the earthquake-resistant equipment to be identified by utilizing the earthquake-resistant test tool clamp by meeting the requirements of relevant industrial standards. The anti-seismic test tool clamp is specified in the anti-seismic identification test guide of HAF-J0053 nuclear equipment to be rigid enough, and the natural frequency of the anti-seismic test tool clamp is more than 33Hz, so that the variation of the input frequency and amplitude of the equipment substrate is not caused.
