Vibration and mechanical shock tests are key ingredients in the engineering development process for space hardware systems. Hardware design margins must anticipate the extreme operational environments that these often massive, large geometry payloads must tolerate during their service life. These severe dynamic environments include:
- Random vibration from rocket engine and aerodynamic inputs
- Low frequency rigid body stress at structural joint interfaces, and
- Transient shock events during launch and staging.
UD performance advances in electrodynamic shaker system design now make it possible to realistically simulate these dynamic environments in the test lab. UD’s Model T2000 shaker, with its 3-inch pk-pk stroke (76 mm) Induct-A-Ring armature, provides extreme-level vibration and shock test capability. In combination with available power amplifiers rated up to 720 KVA output, the T2000 produces staggeringly high acceleration and velocity output. Specific breakthrough performance examples include:
- 154 g rms random on a 16 pound (7 Kg) load
- 100 g peak sine on a 140 pound (64 Kg) load, and
- 135 g peak / 11 milli-second half-sine shock pulse on a 400 pound (182 Kg) load.
