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 four main devices:

  • Arbin
  • Neware
  • Chroma
  • Climatic test chamber

Arbin, Neware, Chroma are three individual DC power & DC load providers for tested battery. Each of them can be used to construct individual battery charge & discharge system accordingly. Arbin and Neware are 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.

3D LASER Scanning And Measurment System

Models to simulate structural vibrations must be validated using reliable experimental data.

Three dimensional scanning laser vibrometry is a unique tool for test and simulation engineers to be able to quickly and very accurately determine operating deflection shapes and eigen modes of complex objects across a wide range of frequencies. Measurement data are only reliable if they reflect the actual vibration characteristics of the real object. This is precisely what the non-contact method guarantees. The PSV-500-3D Scanning Vibrometer was developed to meet the needs in performance, accuracy and data analysis for both structural dynamics testing and ultrasonic evaluations.

LASER Ultrasonics Inspection System

The 105 LUKS-1550-TWM Laser Ultrasonic Kit for Starters are both designed to provide all the components necessary for establishing a laser ultrasonic inspection capability for laboratory use. The kit includes an innovative Adaptive Interferometric Receiver (AIR), as described on the following pages. The fiber-coupled measurement head is small, reconfigurable and easily focused. The modular design allows simple changes of the detection or generation laser, as well as the fiber head.
