摘要
Equipment to be incorporated in payloads to be launched on Ariane-4/5 or on the Shuttle needs realistic environmental test specifications to enhance its cost-effectiveness. A statistical analysis was recently performed to improve the European specifications for sine and random testing at unit level, using test data obtained from sine, random and acoustic testing at system level. These results have been updated using an extended database and improved data processing. In particular, specifications for random testing have been derived in the form of simple continuous functions of the equipment mass, allowing extrapolation to heavy equipment items.
