About Draper

Environmental & Special Test Facilities

Electrodynamic Shakers

  • All classic vibration inputs S, R, S, ... as well as sine on sine, sine on random, burst & chirp,and long time history (>20 min)
  • Hydrostatic torsional arm provides up to 300 deg/s angular inputs
  • Full digital control and analysis data collection
  • 2-, 3- and 16-rail hydrostatic slip tables
  • Autoleveling base, maximizes/minimizes gravitational inputs

Electrodynamic Shakers


Specialty Shakers

  • Provides high-force, high-velocity, large displacements, and low vibrational frequencies
  • Sine, random, and shock capability
  • Autoleveling base
  • Open ends permit optical sighting down rail axis



  • High-speed, high-onset, and heavy-payload precision centrifuges
  • Special viewing windows for high-speed video analysis
  • Full slip ring capability and RF interface
  • Counter rotating platform


Environmental Chambers

  • Pressure-altitude chamber offers high rate of decompression via both roughing and cryogenic pumps
  • Cryopumps allow for deep space vacuum simulation
  • Three optical ports for unit distortion measurements via laser interferometry
  • Temperature humidity chamber simulates environmental effects on a device subjected to atmospheric conditions
