Data and Testbeds

CSIE has access of industrial or experimental data and can perform experiments under different applications, such as for Machinery Fault Simulator Magnum and Battery Test System. The data are available for research upon request.

Machinery Fault Simulator Magnum

Machinery Fault Simulator is a tool for studying signatures of common machinery faults without compromising factory production or profits. The system, which fits on a desktop and weighs about 150 pounds, reflects a modular design that provides versatility, operational simplicity and robustness. Each component of the simulator is machined to high tolerances so it can be operated without any significant conflicting vibration. Then, depending on the situation we want to analyze, we can introduce various faults either individually or jointly in a totally controlled environment. It is an effective tool for introducing the concepts and methodology of predictive maintenance to engineering students. At the same time, the simulator can be used to demonstrate prognostics and systems health management (PHM) implementation methods developed by us in the area of predictive maintenance, e.g. prognosticating of potential fault and remaining useful life. With the Machinery Fault Simulator Magnum, six types of application can be constructed by us:

  • Vibration study(vibration signature study of bearing, gearbox, shaft, rotor, coupling, bearing house, loader, fan, reciprocating mechanism, eccentric sheave and belt-drive )
  • Dynamic friction study
  • Water pump study(study of centrifugal pump with worn impeller and centrifugal pump with clear cover to visualize cavitation)
  • Oil whirl/whip study
  • Compressor study
  • AC motors study(study of AC motor with built-in rotor unbalance, AC motor with built-in rotor misalignment system, AC motor with built-in bowed rotor, AC motor with built-in faulted bearings, AC motor with built-in broken rotor bars, AC motor with stator winding faults and AC motor with voltage unbalance & single phasing)

Battery Test System

The battery test system includes three main devices:

  • Arbin
  • Chroma
  • Climatic test chamber

Arbin and Chroma are two individual DC power & DC load providers for tested battery. Each of them can be used to construct individual battery charge & discharge system accordingly. Arbin is mainly used for battery cell test which has 8 test channels. Chroma can be not only used for single battery cell test but also battery pack test while it is connected with a module named O2. Climatic test chamber is an equipment to provide different climatic environment condition for tested battery, such as high (or low) temperature (or humidity). With these grouped together, battery charge and discharge life test or some dynamic test, such as Federal Urban Driving Schedule (FUDS) and Dynamic Stress Test (DST), etc. can be constructed.
