The statements below refer to the main design drivers for the structure of various parts of a spacecraft. Select all those statements that are correct. Partial credit is available for each correct answer. Select only those statements you know to be correct because negative marking is applied within this question (although it is not possible to get a negative mark for the question overall). In the dynamic response of a whole spacecraft, harmonic (sine) vibration is normally most critical. In the structural design of a space instrument, such as those designed at Leicester, random vibration tends to be a critical loading case In the dynamic response of a whole spacecraft, accoustic vibration is normally most critical. Accoustic vibration modes are excited by vibrations transmitted form the inside of the fairing and through the mounting structure. Random and accoustic vibration is generally driven by a higher frequency input of up to 2000 Hz. In the structural design of large, flat components such as radiator panels or an antenna dish, random vibration tends to be more critical than accoustic. Accoustic vibration modes are excited by vibrations transmitted from the inside of the fairing as sound waves through the air. Random and accoustic vibration is generally driven by a low frequency input up to 100 Hz.
