ABSTRACT:
The process consists in subjecting the component to vibrations and detecting disturbances in the vibrations. The device for the application of this process comprises a vibrator (21) equipped with a swivelling clip (22) in which the component to be tested (23) is fixed. An accelerometer (34) fixed to the vibrating support (30) of the clip delivers an output signal to an electronic circuit which suppresses the low frequencies and which controls indicator lights indicating the acceptance or the refusal of the component. The position of the clip can be modified during the check.
