What clients say:

I have been using XLRotor since 2001. XLRotor is by far the best rotordynamic software on the market. What sets XLRotor apart from others are 1) robust with virtually no bugs, 2) ultra-fast calculation enables quick resolution to analysis problems, 3) comes with many bearing/seals programs, 4) top-rate and unmatched technical support, 5) versatility in modeling, and 6) annual upgrades include useful add-on’s and tools. I strongly recommend XLRotor to any engineering practitioner responsible for bearing/seal/rotordynamics analysis.

Several other analysis programs that integrate with XLRotor are available for additional cost.

XLUVA is a set of XLRotor style drivers for the legacy FORTRAN codes distributed by the University of Virginia. Drivers for four programs are available;

THBRG, fixed geometry journal bearings, version 1.1 or similar
THPAD, tilting pad journal bearings, version 2.16 or similar
DAMBRG, single pad pressure dam bearings, version 2.1 or similar
PDAM2D, multi-pad pressure dam bearings

To use these drivers you must already have working executable versions of these programs in your possession, or else obtain them from the University of Virginia. Rotating Machinery Analysis Incorporated does not supply the actual programs, only the drivers.

The Excel interface drivers make these programs easy to use. The old way to run these codes is to edit cryptic input files, and view results by scanning through long output files. With XLUVA you enter inputs into worksheet cells, select program options from drop down lists, and click a RUN button. An input file is automatically generated for the appropriate code, the program is executed, and results are automatically read from the program’s output file and tabulated on the worksheet. An extensive drop down list of lubricants is also part of these drivers.

The worksheets for these programs can be downloaded for viewing (xluva.zip 39k file)
