Lateral Rotordynamic Analysis

From the design of rotating components for NASA's space shuttle and space station, to the solution of an elusive vibration problem in a large industrial rotating machine, to the development of miniature pump rotating assembly and support bearings used for an artificial heart, RBTS is internationally recognized as an industry leader in providing machinery rotor dynamics engineering services.

With hundreds of successful projects completed, RBTS has developed unparalleled analytical and diagnostic tools and qualifications in the field of rotor dynamics. RBTS provides services to equipment users, packagers, as well as original equipment manufacturers. Our strength is based on our core technical proficiency, continuous improvement to our analytical tools, broad range of experience, and field service support.

Analyzed equipment range from fractional horsepower to 1100 MW and vary in size from a small size turbine (0.10” in diameter, light weight, and speeds in excess of 250,000 rpm) to a large size 66,000 HP Multi-Stage Compressor with Synchronous Motor Drive. Typical analyzed equipment includes:

Centrifugal Compressors
Miniature Pumps
Fuel Pumps
Industrial Pumps
Fans
Mixers
Gearboxes
Generators
Induction Motors (Fixed-Speed & VFD)
Synchronous Motors (Fixed-Speed & VFD)
Spindles (Machine Tools)
Scanners
Jet Engines
Micro Turbines
Turbines (Gas & Steam)
Turbochargers
