Meet the Servo-Pneumatic Four Point Bend Apparatus standalone by CONTROLS Group

The Servo-Pneumatic Four Point Bend Apparatus stand-alone features a pneumatic actuator which is digitally controlled by a pneumatic servo-valve to provide accurate loading in both stress and strain control modes.

 

The Servo-Pneumatic Four Point Bend Apparatus comprises of a pneumatically powered loading system, a beam cradle, an optional environmental chamber, IMACS Integrated Multi-Axis Control System and UTS test application software. The beam cradle has been designed to subject an asphalt beam specimen to four point bending with backlash free rotation and horizontal translation of all load and reaction points.

Some of products features are:

  • Digital servo-controlled pneumatic actuator provides accurate control of loading waveshape
  • Innovative “floating straight-edge” on-specimen transducer eliminates errors due to frame compliance
  • Backlash free rotation and translation on all load and reaction points
  • Sinusoidal or haversine controlled strain or controlled stress loading
  • Constant force motorized specimen clamping • Non-linear regression data fitting ensures reliable determination of phase and modulus.
