Isaac Hong is a Research Assistant Professor in the Department of Mechanical and Aerospace Engineering at The Ohio State University. He received his Ph.D. in Mechanical Engineering from Ohio State in 2019. Dr. Hong also serves as a faculty advisor within the Gear and Power Transmission Research Laboratory (GearLab) at OSU. His research focuses on novel methods to monitor and characterize the structural integrity of power transmission machine elements. This includes developing theoretical models and experimental methods to define fatigue, dynamic response, and tribological characteristics of gears and bearings.
Mechanical power loss in gears is generated through sliding and rolling of the contact resulting in frictional work and elastic hysteresis generation of heat. This action is both a parasitic loss of energy from the drivetrain and a source of engineering costs to control system temperature to avoid heat-related failures of the gearbox components. Therefore, from both a cost and durability standpoint it is of great interest to minimize the frictional losses at the gear tooth contact interface.
