The Dynamics and Vibrations Laboratory specializes in the testing the performances and durability of high-speed rotating machinery and their corresponding gear/belt transmissions, bearing supports, and seal components. Research emphasis are placed the effects of shaft mass-imbalance, shaft misalignment, gear/belt defects, bearing element damage, rotor rub interaction, residual bent of rotor, and excessive vibrations at resonance speeds.

Current research projects include: “Experimental Machine Fault Simulations using Laboratory Models”, “Gear Fault Testing and Benchmarking with Numerical Simulations”, “Vibrations Control Using a Controllable Tilting-Pad Bearing”, “Vibration Signature Analysis Using The Wigner-Ville and The Wavelet Transforms”.

This laboratory is equipped with a 2 ton- Lang shaker, a75-HP gear test rig with attached water brake for gear loads, a SpectraQuest Machinery Fault Simulator, a high-speed contraollable tilting pad bearing test rig, a 1.6 M National Instrument Data Acquisition System, a Bently DVF-II vector filter, and a variety of signal conditioners, B&K acoustic intensity probes, Bently non-contacting proximeters, and PCB accelerometers.
