Abstract：The seismic test for the information processing cabinet of the seismic instrument system WYD1 is introduced.For the test using a 3D vibration table and adopting the multifrequency test mode of the artificial history which is campatible to the response spectrum of the floor on which the equipment is installed,we detected the white noise and carried out the tests of OBE(operational base earthquake) five times and the SSE(safety shutdown earthquake) one time.These tests proved that the seismic instrument system WYD1 can work normally under the effect of earthquake load.
