DAY 1  FLUID-FILM BEARINGS

Monday, Nov. 3 will focus on fluid-film bearings, the vital tribological element of rotating machinery, beginning with their fundamental principles of operation through computer-implemented evaluations of their operational performance characteristics and limitations. Design considerations and applications of fluid-film bearings will be discussed along with the presentation of numerous real-life case histories to illustrate the technology and its application to rotating machinery failure analysis and troubleshooting of common as well as unique vibration problems.

DAY 2 ROTOR DYNAMICS, PART 1

Tuesday, November 4 will focus on rotordynamics. The interacting influence of bearings on the dynamic behavior of rotating machinery will be reviewed and illustrated by the construction of analytical models and evaluated by computerized solutions. Participants are encouraged to present problems to be discussed. Informal technical sessions and workshops are intended to provide participants with adequate time to describe problems they have encountered in bearings, bearing systems, rotor dynamics, and torsional vibration.

DAY 3 ROTOR DYNAMICS, PART 2

Wednesday, November 5 will deal specifically with rotor dynamics as they occur in complete drivelines. Apart from model generation strategies, we present the basics of the analysis of excitability including the interpretation of vibration modes of the drive system. Examples show the steady-state or time-transient response signals generated by the calculations and in comparison with measurement signals.

DAY 4 TORSIONAL VIBRATIONS

Thursday, November 6 addresses torsional vibrations, including case studies and applications in rotating machinery supported by computer simulation methods. This course is recommended as an additional session to the previous days. Complete drivelines are analyzed and evaluated concerning excitability and response capability at specific stations (inertias) and elements (stiffnesses).

DAY 5 SOFTWARE WORKSHOP AND APPLIED EXAMPLES OF REAL-WORLD APPLICATIONS (In-person Only)

Friday, November 7 offers a hands-on workshop using ARMD™ software with demonstration, training, and application to bearings, bearing systems, rotor dynamics, and torsional vibration modeling, analyses, and interpretation of generated results. We will create computer models, demonstrate how to run reasonable computations, and explain how to interpret the computer results. This training covers real industrial case studies.

About the Instructors

He is a pioneer in the development and application of PC-based state-of-the-art computer-aided design software for predicting the dynamics of complex rotor-bearing systems. A former Staff Engineer at the Franklin Institute Research Laboratories and a technical leader at RBTS, he directs government and industry-sponsored projects involving the design, analysis, and troubleshooting of rotating machinery systems and their components. He has been instrumental in teaching and training in the fields of bearings and rotor dynamics, and their application to common as well as unique equipment design, operation, and failure analysis. He taught seminars and training sessions worldwide at rotating equipment OEM, end users, packagers, government agencies, and open seminars to machinery engineers.

Mr. Obeid holds a Bachelor's degree from Drexel University and a Master of Science degree from Penn State University, both in Mechanical Engineering, as well as numerous US & Canadian patents on bearing designs & machinery elements.

DR. ANDREAS LASCHET has more than 40 years of experience in the area of torsional vibrations and has been a teaching partner for this seminar since 2004. As part of his consultation services, Dr. Laschet has carefully investigated CAE methods and simulation algorithms for creating torsional vibration models of complete drivelines and performed detailed studies to verify computer results with measurements.

Dr. Laschet has published more than 60 technical papers and given numerous lectures at international conferences such as VDI, HDT, EFRC, ASME, and SAE. He studied Mechanical Engineering at the University of Technology in Aachen and carried out research work in the field of machine dynamics as a scientific assistant at the Institute of Machine Elements. His thesis "Development of a method for the computer supported simulation of torsional vibrations in drive systems" was published in 1988 as a Springer book “Simulation of the Dynamic Behaviour of Drive Systems” (in German language).

THOMAS GRESHAM has extensive experience in delivering structural analysis, rotordynamics, bearing analysis, seal design, and test planning in addition to teaching sections for Concepts NREC’s advanced turbomachinery engineering training courses.
He brings additional compressor design and rotordynamics engineering experience from his roles as a Compressor Design Engineer at Daikin Applied, a Rotordynamics Engineer at Xdot Engineering & Analysis, and as a Rotordynamics Engineer at Pratt & Whitney in Connecticut.

Mr. Gresham holds B.S. and M.S. degrees in Mechanical Engineering from the University of Virginia, specializing in rotordynamics and vibrations.
