What clients say:

We have been using XLRotor for rotating machinery analysis here at Kato Engineering for the last 15+ years. XLRotor is an important tool in our engineering tool box. The clean Excel based user interface and relative ease of use are just some of the reasons why we use XLRotor. The transient simulation capabilities and bearing stiffness and damping calculation capabilities are additional features that allow for seamless operation in terms of start-to-finish design and simulation capabilities. We have also relied on the timely and knowledgeable technical support.

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)
