WEST LAFAYETTE, Ind. — Researchers in Purdue University’s
College of Engineering could improve the operations of energy-generating
devices such as wind turbines and high-volume manufacturers with their
patent-pending sensor that monitors the performance of bearings.
Anurag Garg, a doctoral candidate in the School of
Electrical and Computer Engineering, said accurate measurements of temperature
and vibration changes can alert workers to premature bearing failure.
“Taking early corrective action could improve safety
conditions for workers, reduce operational downtime and increase bearing life,”
he said. “These lead to more efficient use of resources, improved operational
efficiency and a cost savings of millions of dollars a year for
Conventional bearing sensors that monitor real-time bearing
performance are mounted outside the bearing, which limits the ability to
determine internal conditions.
“The Purdue-developed technology allows a sensor to be
placed directly on the bearing cage, which is the source of temperature and
vibration fluctuations,” Garg said. “As a result, it provides a more reliable
indicator of impending bearing failure and has a better response time than any
commercial sensor available on the market.”
Garg and three other Purdue students formed a group called
Bearing Analytics to present the technology in competitions. Other team members
are Lokesh Gupta, Andrew Kovacs and Christopher Ochynski.
Gupta and Kovacs are doctoral candidates in the School of
Electrical and Computer Engineering. They and Garg are doing doctoral work in
the Adaptive Radio Electronics and Sensors group.
Ochynski is a senior in the School of Electrical and
Computer Engineering and a first-year student in the Master of Business
Administration program at Krannert School of Management.
Bearing Analytics won the Indiana Clean Energy Challenge in
February and are scheduled to compete in the 2013 Midwest Clean Energy Challenge
on April 4 in Chicago. The team also will compete in the national Rice Business
Plan Competition on April 11-13 in Houston.
“We are excited to prepare for the Midwest Clean Energy
Challenge and the Rice Business Plan Competition, two of the most prestigious
events that highlight innovations developed at universities,” Garg said.
“We also acknowledge our mentors who guided the development
of the technology: Dimitrios Peroulis of the School of Electrical and Computer
Engineering and School of Mechanical Engineering, and Farshid Sadeghi and
Douglas Adams of the School of Mechanical Engineering.”
