A number of pieces of experimental equipment have been fitted with sensors and actuators to allow them to be operated remotely. Each of the sensors and actuators is interfaced with a PC running the ReLOAD Experiment Server software, via various data acquisition boards. Each piece of equipment is also monitored via a high speed webcam, to allow the user to observe the experiment as they would in a traditional laboratory session. Details of some of the equipment that is ReLOAD enabled in this way is given below.

 

Vibrating Cantilever Beam

  • University of Leeds, UK

The experimental equipment consists of a steel cantilever beam with strain gauges to record deflection, a shaker that acts as an electro-magnetic damper, an electro magnet to apply an initial deflection to the beam, a web cam to record the motion, all connected to a PC with LabVIEW and ReLOAD data acquisition software.

Using ReLOAD, the amount of damping applied to the beam can be changed and its affects on the beam's response recorded.


Position Servo Motor

  • University of Leeds, UK

The experimental equipment is housed in two boxes connected to each other by a ribbon cable. One box contains the controller, which is connected to a PC with LabVIEW and ReLOAD data acquisition software and the second houses the motor and gearbox which is connected to a tachogenerator and output position potentiometer.

Using ReLOAD, P1, the Forward Path gain and and P2, the Velocity Feedback Gain, can be varied and its affects on the motor's response recorded.


Smart Lumped Mass Cantilever Beam

  • University of Leeds, UK

The experimental equipment consists of an aluminium lumped mass cantilever beam with strain gauges, lasor sensors and minature accelerometers to capture the structures motion, a shaker used to apply active damping, an electro magnet to apply an initial deflection to the beam, a web cam to record the motion, all connected to a PC with LabVIEW and ReLOAD data acquisition software.

Using ReLOAD, the amount of damping applied to the beam can be changed and its affects on the beam's response recorded.
