Course description
The Rotordynamics short course is suitable for engineering staff wishing to acquire an effective command of Rotordynamics through a learning route which combines understanding of indispensable aspects of the basic theory together with the technical insight which is obtained from the comprehension of the physics through practical demonstrations. As such the course is targeted for industry delegates who are interested in the topic from the perspective of users rather than those whose focus is primarily on the theoretical aspects of this branch of engineering science.
With typical delegates covering rotating machine design, equipment selection or rotating equipment field engineers.
Upcoming start dates
Suitability - Who should attend?
The course is designed for personnel who are dealing with the design of rotating machines be it in Oil and Gas, power generation or automotive. Also, it is designed for engineers who are operation oriented to enhance their asset availability and reliability as well as rotating machines preventive maintenance optimisation and components upgrade and retrofit.
Although the course is suitable for engineers with minimal previous exposure to Rotordynamics, it would also be useful for staff with limited experience in the field but who wish to consolidate their own understanding of the subject through a guided review of the basics together with the contact with advanced aspects of the topic and its active application in an industrial setting.
Outcome / Qualification etc.

- Demonstrate the ability to solve design problems varying from consumer annoyance to machine survival.
- Be aware of the different techniques used in industry for the analysis of rotordynamic problems.
Training Course Content
Core content
This Short Course provides a broad introduction to the fundamentals of rotordynamic behaviour and to the evaluation of rotating machinery. The fundamental principles and mechanics involved will be explained with a focus on the practical interpretation and understanding of the rotordynamic phenomena experienced by rotating machines of almost all types.
Working from these fundamental characteristics, the key methods of assessing and interpreting the performance of rotating machines, such as critical speed maps, rotordynamic performance plots alongside the interpretation of actual machine measurements, are addressed.
The use of simple rotors will be introduced as a means of demonstrating and understanding the rotordynamic behaviours experienced by more complex rotors. The behaviour of bearings, rotor support structures, sealing arrangements, rotor unbalance and rotor balancing will also be considered, and an overview of how these components impact on the rotordynamics will be introduced and discussed.
The course will include an introduction, and some hands-on application, to the analytical methods used to solve and assess the behaviour of real rotors using state of the art software tools. Through several real rotor case studies, the principles and performance measures covered early in the course will be practically applied by the delegates through the use of modern rotordynamic software tools.
The Key Topic Areas covered in the Course:
- Introduction to Rotordynamics and what this means for real machines
- Practical explanation and exploration of the fundamental characteristics of rotor dynamics and how this relates to rotating machines, such as: -
Natural frequencies
Critical speeds
Rotor mode shapes
Jeffcott rotors
Shaft whirl - Lateral and torsional vibration of rotors
- Rotor unbalance and balancing methods
- Influence of rotor bearing supports and types (hydrodynamic bearings and seals)
- Practical modelling methods and hands-on application of modelling rotors
- Real rotor case studies with hands-on modelling exploring the impact on rotor behaviour and performanceI
- Interpretation and presentation of rotordynamic results of modelled and real rotors
The course will also provide an opportunity for open discussion on delegate rotordynamic experiences and machine applications. The course has a strong practical focus, whilst also covering the necessary introduction to the analytical theories involved.
The course will provide a sound footing for currently practicing engineers or those newly entering the field of rotating machines, as well as acting as a refresher course for those involved in the design or field operation of rotating machinery.
Course delivery details
Course structure
This course is delivered over five days and is mostly in the form of lectures, tutorials, and case studies. All delegates will receive A Certificate of Attendance at the end of the course. The course will be delivered face-to-face at the Cranfield University campus and, simultaneously, broadcast live online. Consequently delegates can either register to attend the lectures in person or register to join the interactive lectures online.
