Vibrations

mcdaniel-lab-sqIs motion about an equilibrium point. At the human scale, a vast amount of research is aimed at reducing vibrations in order to reduce the associated noise. To achieve this reduction, our research is investigating the design and deployment of damping materials such as advanced composites. We also explore the vibrations of complex systems excited by force systems that are not well understood, such automotive brake assemblies. This work will eventually provide solutions for automotive brake squeal, which currently costs automotive companies approximately one billion dollars per year in North America alone. At the MEMS scale, our research investigates the vibration of high-Q resonators that are essential to cell phone and lab-on-chip technologies. In addition to improving the built world, our work investigates vibrations in the natural world. In collaboration with biologists at Boston University, recent work has investigated the escape hatching of the red-eyed tree frog due to vibrational cues from predators.

The vibrations laboratory offers a full suite of sensors, instrumentation, and software necessary to research the vibrations of complex structures and technologies that reduce vibration and noise.

One area of current interest is the spatial mapping of energy removal by damping treatments in order to better design damping treatments for complex structures. Another area is the mitigation of automotive break squeal.
