Combined with the demand of the metrology institution for the base strain sensitivity test of the(vibration and shock Transducer),and the lack of the test device based on free vibration,the research of the base strain sen-sitivity testing device of the(vibration and shock Transducer)based on steady-state sinusoidal excitation is car-ried out,including mechanical system,steady-state sinusoidal base strain control system,measurement system,etc.,and the controllable steady-state base strain is generated in the range of(1~6)Hz by electromagnetic exci-tation.This enables testing of the base strain sensitivity of the base(vibration and shock Transducer).
