Course contents *

The course presents the theories of machine dynamics, how to model and simulate dynamic behaviour of machine systems in both time and frequency domains and how to transform the responses between these domains. In the course, technology and methods for load and vibration measurements are also introduced, and exercises on performing such measurements and analysing the measurement results are carried out. Furthermore, parameter identification and inverse modelling are discussed and practised.

Intended learning outcomes *

On completion of the course, the student should be able to:

• model the dynamic behaviour of machine components and systems using Matlab and Ansys;

• analyse the frequencies contained in a measured dynamic response;

• identify dynamic system properties from data in vibration measurements;

• carry out inverse modelling of a dynamic machine system.

Course Disposition

• Lessons (10 x 2 hours): Lessons deal with dynamic systems, simulations in the time domain, simulations in the frequency domain, technology to measure dynamic loads and vibrations, transformations between time and frequency domains, identification of damping and friction losses, and the inverse modelling of dynamic systems.

• Physical laboratory sessions (4 x 2 hours): Laboratory sessions in measurement.

• Computer exercises (4 x 2 hours): Modelling and simulation exercises in computer lab.

• Group assignments (scheduled supervision).

• Homework assignments (not scheduled time).

Specific prerequisites *

A Bachelor's degree in mechanical engineering or the equivalent.

Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.

The examiner may apply another examination format when re-examining individual students.

ÖVN1 - Passed laboratory sessions and written assignments, 3 credits, grading scale P/F

TEN1 - Written examination, 3 credits, grading scale A-F

The final grade is based on the grading of TEN1
