ISCORMA-3 Summary

    ISCORMA-3 was held 19-23 September 2005, in the Crowne Plaza Cleveland City Centre Hotel in Cleveland, Ohio, USA, a beautiful city of unique buildings situated on the shores of Lake Erie. Many of the guestrooms had a view of the lake, and breakfast was provided each day to attendees who were staying in the hotel.

    The Organizing Committee consisted of the following: Donald E. Bently, Chairman; Jerzy T. Sawicki, Vice Chairman, and A. Muszynska, R. C. Hendricks, D. P. Fleming, and Z. Gosiewski. They worked throughout the previous two years collecting and conducting the review process for 86 papers submitted to the conference regarding the causes, behavior, and alleviation of instability phenomena in rotating machinery.

    ISCORMA-3 opened with the Welcoming Reception on Monday evening from 6 to 8 p.m. in the sixth floor ballroom. After brief introductions by Donald E. Bently, Chairman and CEO of Bently Pressurized Bearing Company, and Professor Jerzy Sawicki of Cleveland State University, the guests were welcomed to the Cleveland area by Dr. Michael Schwartz, President of Cleveland State University.

    The conference registration desk and all the session rooms were located on the sixth floor of the hotel. Registration opened at 2 p.m. on Monday, 19 September, and closed after the final sessions on Thursday, 22 September. Those attending at the desk included Jeanette Cox, Carol Money, and Sue Thomas, all from Bently Pressurized Bearing Company.

    Participants of the conference numbered 73 and came from 18 countries. As noted below, they rated the conference good/excellent on scope, technical content, relevance, organization, hotel, and social events (see statistics below).

    During the three days of parallel sessions, 60 papers were presented. The sessions included the following topics: Monitoring of Rotating Machinery, General Rotor Dynamics, Rotor/Bearing Systems, Rotating Machine Malfunctions, Statistical Models, Fluid Bearings, Cracked Rotor, Rotor/Bearing Stability, Vibration Control, Gas Bearings,, Turbine Malfunctions, Rotor/Tilting Pad Bearings, Rotor-to-Stationary Part Rubbing, Unbalance Effects, Rotor/Seal Problems, and Cracks in Machine Elements.

    The Keynote Speaker was Professor Chong-Won Lee from Center for Noise and Vibration Control (NOVIC), KAIST, in South Korea. His topic was entitled, "Stability and Strength of Modes in Rotating Machinery."

    Two co-chairs were assigned to each session to introduce the speakers, lead discussions, and control timing. Each paper was assigned 25 minutes, including the discussion. A student was assigned to each room to make sure all equipment was running well. These included Anand Parey from Indian Institute of Technology in India, and Andreas Johannson and Kumar Nale from Cleveland State University.

    Each participant received in their conference bag a combination pen and laser pointer. These came in handy during the presentations for each participant.

    The Awards Dinner was held Wednesday evening in the Fuldheim Ballroom off the hotel lobby. After a delicious dinner, the following awards were given:

Best Student Paper

  • "Identification of Anisotropy Asymmetry in Rotor System From Directional Frequency Response Estimates," by Y.-H. Seo, S.-W. Kang, and C.-W. Lee. Presentation was to Y.-H. Seo.

Outstanding Papers

  • "Effects of Dampng and Friction of the Rotor/Seal or Retainer Bearing Full Annular Rub," by A. Muszynska and J. J. Yu. Presentation was to A. Muszynska.
  • "Some Considerations on Cyclic Asymmetry in Rotordynamics," by G. Genta and M. Silvagni. Presentation was to G. Genta
  • "Increasing the Stability Threshold of a Rotor by Open-Loop Control of the Bearing Mount Stiffness," by H. Ecker and A. Tondl. Presentation to both authors.

Special Silver Award

  • Presented to Zdzislaw Gosiewski for his contribution to magnetic bearing rotordynamics technology.

    After presentation of the awards, drawings were held to give away books donated by their authors: "Fundamentals of Rotating Machinery Diagnostics," by Donald E. Bently and Charles T. Hatch (the winner was Tsuyoshi Inoue), and "Mechanics," by Agnes Muszynska (winner was Gordon Kirk).

    Thursday evening a group of 32 participants and staff was carried by Lolly the Trolley to the Great Lakes Theater Festival to see the stage play, Amadeus. It was very much enjoyed by those in attendance.

    The second social event was a tour Friday to Wright-Patterson Air Force Base. At 7 a.m. 28 people boarded a comfortable bus provided by Great Day! Tours. It took about 3-1/2 hours to arrive in Dayton, Ohio, where the air base is located. When we arrived, we were each given a box lunch to eat before we went into the museum. The display of airplanes was very spectacular. Most participants caught a bus, after providing appropriate identification, and went onto the base where the retired presidential planes are housed. We were allowed to walk through each plane.

    After about 3 hours touring the museum, we went into the IMAX theatre and saw an informative and entertaining movie about flying. We had a few minutes to go to the gift shop or whatever we wanted to do before boarding the bus for the return trip.

    In Bellville, Ohio, the bus stopped for dinner in an Amish restaurant, where we were served a delicious dinner (family style). There was a gift shop there that was enticing to most.

    We arrived back at the hotel about 10 p.m. after a fun-filled day.
