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.

Testimonials

Your input is important to us. Please provide your valuable feedback. Here are some testimonials from our clients:

 I have known Brian Murphy since the days of RAPP and PUP. XLRotor is an excellent rotor dynamic analysis software. I have been using XLRotor since its inception and found the program to be very user friendly and easy to learn. The spreadsheet format allows varying degrees of analysis in a time efficient manner, quick and easy checks on the input data, and flexible format plots to satisfy changing customer needs and API requirements. The bearing and seal codes are tops in the industry. If you have any questions on the software or rotor dynamics in general, Brian and Daniel are tops in their field and respond in a timely manner.

 XLRotor is fast, and because XLRotor models are transportable to our clients and suppliers, we can easily share results and make difficult decisions in a minimum amount of time. I should also note that the capability and functionality of XLRotor continues to expand. As far as support, Dr. Murphy responds almost immediately to any questions or issues we may have

 The fact that XLRotor is imbedded in Microsoft Excel shortens the learning curve for new users and makes it easy to import and export data to other applications. The charting functions are very familiar and enhanced functionality can be obtained by using Visual Basic calls. The numerous example problems included with XLRotor can be used to kick start most modeling efforts.

 XLRotor is easy and flexible to work with. The Excel data input interface and graphical presentation tools has helped us carry out extensive and detailed rotordynamic analyses with varying design parameters for our clients within tight schedules. The program is stable and fast and the access to bearing data base modules a great help.

 A significant part of our business involves the design and analysis of high performance rotating machines. XLRotor, with its automated features eliminate time consuming tasks such as formatting and charting, reduces the time spent on rotordynamic assessments and enables updates to be quickly carried out as a design progresses. This results in reduced overall design and analysis times, thereby enabling us to provide a very efficient and cost effective service to our clients.

 Being a regular XLRotor user, I am impressed with its breadth and depth. One can be productive with this tool at any level of experience. The Xcel format gives you the ability to customize your tools to your liking. Just as important, this program has useful example projects and one of the best help files I have ever used. While most of my questions are answered in the thorough help file, service is exceptionally prompt when needed and just an email away. XLHydroDyn is a fantastic complement and is highly recommended.

 The Excel based platform for XLRotor is easy to use and makes it easy to keep all pieces of an analysis together and documented in a common location. Dr. Murphy has steadily enhanced the program over the 20+ years I have used it by adding new analysis features, numerous bearing and seal models, and new input/output formats. It is a living program that gets better and better every year.
