This may be a basic question, but I have been struggling with it the past few weeks. I am working on a spacecraft project (and I am new to this industry), and there are some concerns that when the spacecraft is subjected to the sine sweep qualification testing, some of the fragile equipment may not survive the test. Therefore, given the input sine sweep profile that is the test requirement, how do you go about notching the levels down to something "less damaging" and yet meeting the test objective i.e. to qualify the equipment to launch loads. I have been reading about force-limited testing, but I think this method is more suitable for random vibration testing. I have seen some materials pertaining to sine sweep testing, but there's little information on how to derive the notch profile. Any pointers would be deeply appreciated. Thank you.
