Description

Advanced vibrations of discrete and continuous systems in mechanical and mechatronics engineering

The course builds on the knowledge of previous basic dynamic, mechanics and vibration courses. The overarching theme of the course is learning how to predict the performance of oscillating systems as we can observe them in everyday life. Thereby vibrations will first be classified by mechanisms followed by learning associated solution approaches for each type of vibration. A more detailed content is as follows (in no particular order):

• Classification of vibrations, review of fundamental terminology and key concepts
• How to recognise and analyse parametrically excited systems (incl. Lab)
• How to recognise and analyse self-excited systems: example tool chatter (machining vibrations)
• Introduction to nonlinear vibration analysis
• Multi-degree-of-freedom system: stability and dynamic performance
• Vibration analysis in frequency domain (FFT, DFT)
• Continua (rod, string, beam, plate)
• Experimental transfer function and modal analysis (incl. Lab)

Learning Outcomes

Factual Knowledge: students will be able to recall and correctly apply standard and advanced terminology related to oscillating systems and their analysis (examples: resonance, parametric resonance, time and frequency domain analysis, etc.)

Comprehension & Analysis: students will own a library of analytical, computational and experimental methods and routines for correctly analysing oscillating systems and to confidently interpret results and their technological meanings

Application: students will be able to correctly apply taught theoretical, computational and experimental methods to unfamiliar situations, including real-life engineering problems

Synthesis: based on results from an analysis students will be able to make informed decisions to either improve the performance of e.g. a design or process, or to guide the development of an entirely new product and/or innovation

Professional Communication: professional formulation and presentation of results are emphasized on in form of report writing in this course

Self-Evaluation: students will be able to think critically about and defend results of an analysis; they will be positioned to make informed conclusions and give constructive recommendations, to correctly evaluate and criticize obtained results and/or data.
