DSM was contracted by the Boeing Corporation to develop a complete proof-mass shaker system. The system consisted of a low profile, high force shaker, an arbitrary waveform generator, and an efficient amplifier for use in testing the limits of the current active and passive vibration suppression systems aboard the International Space Station (ISS). The technology within the shaker was developed through a BMDO-funded SBIR program for piezoelectric vibration suppression actuators.
Within three months DSM designed, developed, produced and delivered a demonstration system for Boeing to test. One month later, DSM was able to deliver a MIL-I flight qualified unit. The shaker system was subsequently delivered to the ISS by the Space Shuttle Endeavor.
