Vibration Test Requirements and Application Analysis of Civil Aircraft Equipment (I) Vibration Test Requirements of Civil Fixed-wing Aircraft Equipment in DO 160F/G

The paper set forth the characteristics of the vibration environment of civil aircraft equipment and the classification of vibration tests. The vibration test requirements of various civil aircraft equipment in DO 160F/G were concluded and summarized, including vibration spectrum, magnitude and duration, and then were analyzed and explained accordingly, so as to facilitate the reference and application thereof. At last, the application of vibration test method for civil aircraft equipment was generalized. Vibration test requirements of civil fixed-wing aircraft equipment was described and classified according to the different sections of the equipment in the aircraft. The vibration test requirements of the equipment at each position were described in details by contrast; and the vibration test requirements of the airborne equipment of civil helicopters was presented.
