Working Principles Principles of Design Simple Control Concepts Dr. Paul Allaire Sandye Simmons Retired Chaired Professor at University of Virginia, Long Time Director of Rotating Machinery and Controls Laboratory (ROMAC) Founder and Director of Center for Magnetic Bearings Chief Technical Director, RBSI Dr. Tim Dimond, P.E. President – Rotor Bearing Solutions International Formerly Principal Scientist in ROMAC Extensive work in rotordynamics, bearing design, and rotordynamic system identification. BSME University of Virginia TurboCare, Inc. Manager Steam Turbine Applications 33 years Industry Experience Tom Smith TurboCare, Inc. Manager, Steam Turbine Technology Integration, Service and Repair 41 years Industry Experience Lectures and Notes Most of the lectures have been prepared by Paul Allaire and Tim Dimond in the form of a future textbook. These notes are very detailed and the same ones used for lectures in the rotordynamics and bearings courses taught at the University of Virginia by Prof. Allaire and Dr. Dimond in recent years, to ROMAC graduate students, as well as some new material in the same form. Unlike many industrial seminars (short courses) taught by other lecturers who use Power Point slide that leave views wondering what steps were followed in going from one slide to the next, these notes read just like a textbook when readers go back to them 6 months or years later. Full copies of all of these notes will be provides to the attendees in electronic form. Some other lecturers will be delivered in Power Point or equivalent form but all of those talks will also be provided to the attendees in electronic form. The lectures in electronic form can be viewed on attendees’ personal computers during the seminar lectures. In the lectures, the mathematics behind the rotordynamics calculations will not be emphasized in the lectures and will only be summarized. Generally the mathematics behind the case histories will not be discussed at all. However, for those interested in the mathematical background, the equations are included in the notes.
