Rotordynamics Modeling of ALL Turbomachinery

If it rotates fast, you need to model it, fast.

 We specialize in advanced rotordynamics modeling for all kinds of systems.  This includes modern Oil-Free Machinery® on foil bearings (of course!) but also oil-free magnetic bearing systems.  


Oil and Gas equipment is where we started in this business, so conventional and complex Oil and Gas equipment such as industrial pumps, turbines, gear boxes, and more on ball bearings, journal bearings and seals.  This includes both lateral and torsional (the "silent killer") modeling, as needed. 


Rush jobs are OK.  And common.


We exclusively use XLRotor which provides a customer-readable Excel file as the final output.
