 I've used XLRotor since its inception in the mid 90's and found the program to be very user friendly and easy to learn. The spreadsheet format allows varying degrees of analysis depth in a time efficient manner, quick and easy checks on the input data, and flexible format plots to satisfy changing customer needs and requirements.

 Using XL-Rotor for 15 years now, I have to admit that this is a very powerful and comprehensive tool, intuitive and very user friendly. Really flexible through Excel, it is easy to add macros with high added value that greatly ease everyday use. Also the hotline is super responsive and helpful, if the need may arise.

 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.

 I recommend XLRotor for anyone doing rotordynamic analyses, from beginners through experts. I have been a user of XLRotor for over 15 years, and am currently vice chairman of API 684, Rotordynamics. I find XLRotor very user friendly since the interface is in Excel, a program I’m already familiar with. XLRotor is capable of performing detailed analyses of lateral and torsional systems. Whenever I need help with an analysis or understanding the program methods, Dr. Murphy is always available to assist quickly and efficiently.

 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.
