Figure 1. Space Shuttle Orbiter Ku-band Antenna Introduction Mechanical vibration is usually undesirable in a structure because it can lead to fatigue and other types of failures. Vibration does have its beneficial uses, however. For example, dither vibration was used to ensure that the Space… Read more

Stentor Satellite Equipment mounted in satellites must withstand acoustic-driven random vibration at liftoff and during the transonic and maximum dynamic pressure phases of flight. The equipment must be designed and test accordingly. The equipment is mounted on shaker tables for the random vibration testing,… Read more
Introduction Spacecraft must withstand vibration from pre-launch transportation and from powered flight. The spacecraft is not powered during these events. In addition, a spacecraft must withstand “microvibration” or “jitter” from its own moving parts once it reaches orbit and becomes operational. This vibration is… Read more
