The impact testing facility composed of:hailstone impact

  • a gas cannon that operates with pressurized nitrogen.
  • a protective polycarbonate chamber, practically bulletproof.
  • high-speed imaging apparatus, up to 500k fps.

The facility if capable of

  • Ultra High Frequency signal generation and acquisition systems (1-10MHz).
  • High Frequency (1-1MHz) amplifier for active piezoceramic sensor pairs.
  • Laser Doppler Vibrometer (Polytek) non-conduct sensor with high velocity and displacement resolution, and high sampling-frequency (300ksamples/sec).

SHMLab

  • Acceleration (1D and 3D), force, strain and temperature measurement
  • Impact force excitation through a range of impact hammers (miniature to heavy)
  • Continuous force excitation (6lb and 50lb electromagnetic shakers)
  • 8- and 4-channel high-speed dynamic data acquisition & spectral analyzer systems
  • Modal frequency, damping and mode shapes measurement
  • Composite Damping Characterization

The Smart Material Testing Lab is employed for:

  • Testing of piezoelectric actuators & sensorsAdaptiveStructuresFacility
  • Thermomechanical testing and stabilization of SMA actuators
  • High-voltage, high-frequency amplifiers for the excitation of piezo-actuators (±700Volts, 0-100kHz)
  • Active Shape and Vibration Control
  • High-speed, high-precision dynamic data acquisition systems
