Study on design method for reliability vibration test profile of ship-borne equipment

A method based on the measured data to design reliability vibration test profile of ship-borne equipment was proposed. The parameter hypothesis test of mathematical statistics theory was applied to analyze vibration environment measured data of ship-borne equipment and obtain characteristic samples of different statuses in different regions. The upper tolerance limits method was applied, which was corrected to induce random vibration normalized spectrums of characteristic samples. Test time was determined according to the ship-borne equipment's mission profile. The results show that this method has a perfect theory and lays a foundation for reliability assessment of vibration environment for ship-borne equipment.
