The Energy and Tribology Laboratory

Applications3.jpg

We study the science of friction, lubrication, and wear within sliding and contacting interfaces. Our work incorporates analytical, numerical, and experimental techniques in order to analyze the interfacial interactions and wear between sliding surfaces in both dry sliding or lubricated contact. Since friction, lubrication, and wear is a challenge for every device that contains moving components, our work extends to a number of industries, including power generation, energy conversion, energy harvesting, MEMS, and health sciences.

Our Research Interests

The Energy and Tribology Laboratory is interested in the interfacial science of sliding surfaces. To this end, the laboratory is concerned with three areas wherein tribology is known to take a significant role:
  • Rolling-Sliding Contact - Experienced between surfaces that have both rolling and sliding components.
  • Low Amplitude Reciprocating Contact - Experienced between contacting surfaces with small oscillatory motions.
  • Micro- and Nano-Scale Contact - Experienced between micro- and nano-scale devices, where stiction and adhesion are common.
