LAUNCH PAD: Environmental vibration and acoustic testing on spacecraft can play a major role in ensuring safe launches and deployment

摘要

Vibration and high-intensity acoustic pressure during launch can damage spacecraft structures. Therefore satellites are subjected to extensive analysis and testing to ensure survivability during launch and deployment. The typical satellite structure is not homogeneous, having several substructures such as antennas, solar panels and externally mounted cameras attached to it. Consequently, the launch experience of a satellite consists of vastly different motions at different points of time.
