#720X - Bearings, Rotor Dynamics and Vibration Analysis

Course Objective

Upon completion of this course, participants will have gained a thorough understanding of the design, application, and reliability evaluation of bearings in rotating machinery applications. They will also learn about rotor dynamics and vibration analysis as it relates to machinery condition monitoring systems.

Who Should Attend

Both engineers without previous experience with bearing systems, and as a refresher for experienced engineers with rotating machinery responsibilities. Also, engineers, technologists, and other operational personnel who have machinery vibration analysis responsibilities. Specific applications and case histories will be discussed as the relevant topic is presented.

Course Description

This course is divided into the main sections: 

Day 1 - Bearings

BASICS OF BEARING SYSTEMS

BEARING COMPONENTS

BEARING LUBRICANTS

Day 2 - Bearings (cont'd)

This day provides students with a better comprehension of the design, application, and life potential of all bearings in contemporary turbomachinery. Practical examples and case histories will be discussed.

BEARING TYPES

MANUFACTURING TOLERANCES AND INTERNAL CLEARANCES

FAILURE MODES

BEARING STRESSES AND FATIGUE LIFE

LUBRICATION AND BEARING KINEMATICS

Elastohydrodynamic (EHD) lubrication, film thickness, low-speed vs. high-speed, skidding, time transients

MATERIALS AND PROCESSING

MULTI BEARING SYSTEMS

Fixed bearings, floating bearings, service factors for each bearing posistion

Day 3 - Rotor Dynamics and Vibration

On this day, the basics of vibration analysis will be discussed. Bearing peformance is primarily monitored by vibration analysis and temperature analysis, both of which may be integrated into a machinery train's condition monitoring system.

Day 4 - Vibration Analysis

Day 5 - Vibration Analysis and Other Aspects of Engine Condition Monitoring Systems

Course Duration - 5 days
