Rotor Dynamics & Bearings Technologies (Lateral / Torsional Vibration Analysis & Fluid-Film Bearings)
Technical understanding of bearings and lateral and torsional rotor dynamics emphasizing bearing design, function, and influence on lateral vibrations, as well as, the general vibrational behavior of rotating machinery and strategies to improve its rotor dynamic performance.
Overview
In depth understanding of the operational characteristics of fluid-film bearings in turbomachinery which includes, their behavior to such effects as installed clearances, supply lubricant properties (type, temperature, pressure, flow rate) coupled with their effects on machinery vibration levels, instability and safe operation.
The rotor dynamics and torsional vibration sessions will provide the fundamental and advanced understanding of rotating machinery dynamics and their vibration characteristics influenced by such conditions as their operating speed (or speed range), balance level, resonance and critical speed, shaft flexibility, required separation margins from their designed conditions and effect of support structural flexibility.
Designed For
This comprehensive “Technology Transfer” virtual course is designed for engineers and technical managers who are involved in rotating machinery design, operation, maintenance, diagnostics, and troubleshooting, with emphasis on bearings and bearings systems, machinery rotor dynamics, and drive train torsional vibration.
