New Series on Rotordynamics: Preface

Next Blog

Welcome to our latest blog series on rotor dynamics! In this series we’ll be covering fundamentals and a general overview of the engineering discipline that is rotor dynamics, including some basic definitions, why it’s important, the different calculations, and the overall objectives and purposes for these calculations.

In the months ahead, you can expect to learn more about:


This series will endeavor to get readers’ feet wet in the world of rotor dynamics, which is still considered a niche discipline of rotating equipment and turbomachinery engineering. Despite being such a niche subdiscipline of mechanical engineering though, it’s crucial for the safe operation of turbomachinery and high-speed rotating equipment. As we’ll learn, failure to take rotor dynamics into account can have disastrous results. So stay tuned for further editions in this series; we hope you learn something new, whether you’re brand new to rotor dynamics or a seasoned veteran in the field!

Coming up in next month’s rotation…

In the next blog, we’ll cover the basic definition of what rotor dynamics is, as well as where rotor dynamics is considered. You can read an excerpt of the next post below:

Rotor dynamics is a branch of applied mechanics in mechanical engineering and is concerned with the behavior of all rotating equipment; considering phenomena like vibration, resonances, stability, and balancing. It accounts for many effects: from bearings, seals, supports, loads and other components that can act on the rotating system. Unaddressed, such phenomena can significantly shorten the life of or even destroy a machine. So where can rotor dynamics be found?


Well, unsurprisingly, the answer lies in the name, rotor. Anywhere that a rotating machine is used such as a turbine, compressor, pump, electric motor, turbocharger, or even a reciprocating machine, rotor dynamics analyses are (and should be!) performed. In terms of industry, this discipline is common throughout the power generation, oil and gas, automotive, and aviation industries to name a few, as well as marine transportation.
