Paper on the Integral Squeeze Film Damper (ISFD

Waukesha Bearings®, a global leader in the design and manufacture of oil and process-lubricated engineered bearings, is proud to offer the presentation of the integral squeeze film damper (ISFD) 8 – 10 a.m. June 19, at the American Society of Mechanical Engineers (ASME) Turbo Expo in Düsseldorf, Germany.

The presentation is based on a paper that presents experimental tests and analytical results focused on stabilizing a 46 MW 6,230kg utility steam turbine experiencing subsynchronous rotordynamic instability. The paper, coauthored by Dr. Jong Kim, Sr. Principal Engineer of Waukesha Bearings, and several other ASME colleagues, advances an integral squeeze film damper (ISFD) solution which was implemented to resolve the subsynchronous vibration and allow full-load and full-speed operation of the machine.

Dr. Jong Kim is Senior Principal Engineer for Waukesha Bearings. Joining KMC/BPI in 2001, he possesses extensive experience in rotordynamic analyses and bearing failure analyses. A former mechanical engineering teacher at Korea Maritime University for 10 years, Dr. Jong Kim received a BS degree (Mechanical Engineering, 1985) from Busan National University, and an MS degree (Mechanical Engineering, 1987) and a PhD (Mechanical Engineering, 1991) from KAIST (Korea Advanced Institute of Science and Technology). He has authored and coauthored several technical papers and holds patents on bearings and dampers.
