What clients say:

The XLRotor is flexible, embeddable, and sharable. This makes it much easier for our team to deal with complex loading conditions and sensitivity tests. It also provides a simple communication process with our teammates and customers. The modeling is straightforward with abundant examples to learn from and use. Moreover, the technical support from Dr. Murphy is extremely helpful and insightful.

About Dr. Murphy

Dr. Murphy received his undergraduate and graduate degrees in Mechanical Engineering from the University of Florida (1978) and Texas A&M University (1984), respectively. At Texas A&M he taught undergraduate classes, and performed research in the field of dynamics of high speed rotating machinery.

From 1984 to 1992 he worked at the Rocketdyne Division of Rockwell International, where he performed research and development for analysis and testing in the areas of structural dynamics and rotor dynamics for liquid rocket engine turbomachinery. He played key roles in the development of new advanced bearing and seal technologies for high performance rotating machines, including ultra high speed rolling element bearings, magnetic bearings, high pressure hydrostatic fluid film bearings, and high pressure pump seals. During those years he also served as part time faculty at the California State University in Northridge, CA, teaching senior level machinery dynamics.

In 1988 he was a founding partner in an engineering consulting firm. In 1992 he left Rocketdyne to devote full time to that effort, now called RSR, Incorporated. Within that organization he performed field troubleshooting of machinery vibration problems, developed and marketed computer software for rotating machinery dynamic analysis, and consulted to industry on the design and analysis of high performance rotating machines.

From 1993 to 2014 he was on the staff of the Center for Electromechanics at the University of Texas at Austin, where he performed research related to high performance rotating machinery. This included analysis and design of high performance electromechanical machinery such as motors, generators, and energy storage flywheels. Other areas of research included design, analysis and manufacturing of high performance filament wound composite structures, with emphasis on application to high speed rotors.

In 2014 he left the University of Texas to devote full time to RMA, Inc. and the continued development of XLRotor.

Dr. Murphy has authored or co-authored more than 40 papers, and contributes extensively to industry symposia and conferences. He also is a sponsor and administrator of www.rotordynamics.org, a searchable online bibliographic index of about 25,000 books, scholarly papers, and other publications dedicated to rotordynamics.
