Rotordynamics

Attendees must bring a laptop to the course. Materials will be distributed on USB sticks and via Filex.

Instructed by A Leading Industry Expert:

Malcolm Leader

Malcolm E. Leader, P.E. is a Turbomachinery Consultant and Owner of Applied Machinery Dynamics in Durango, Colorado. He is currently involved in the design, testing, modification, and installation of rotating equipment. He spends time doing theoretical design audits and working in the field implementing changes and overseeing installations. Mr. Leader has written several papers on the subjects of experimental rotordynamics, bearing design, design audits for rotating equipment, and practical implementation of rotordynamic programs.

Why You Should Attend
This course is for beginning and intermediate level engineers in the petroleum, chemical, power, and gas industries or anyone interested in the dynamics of rotating machinery. The emphasis is on turbomachines such as turbines, compressors, expanders, motors, pumps, and generators. The intent is to understand the rotordynamics of these machines and their subcomponents to help select, analyze, troubleshoot and repair them for maximum reliability and minimum vibration problems. This is not a math intensive course. Case histories and several workshops for hands-on evaluation of actual machines will be given.
