Random Vibration Load Factors

Wijker, Jaap

Abstract In general, the structural design of spacecraft structures, instruments, and structural elements is based on the static load factors specified in the launch vehicle (L/V) user’s guide(s) or by other quasi-static load (QSL) specifications. In this chapter, the calculated random load factors are based on the $3 σ$ values of the interface loads of a particular system and depend on the random load levels, natural frequencies, and associated modal effective masses. If the random load factors are beyond the specified quasi-static load factors, adaptation (notching) of the random dynamic loads may be considered. Examples and problems with answers included are provided.
