Description including Unit Aims

The aim of this course is to develop an understanding of basic vibration phenomena and properties of single and two-degree-of-freedom vibrating systems. This course also provides introduction to basic aeroelastic phenomena in aerospace context.

Intended Learning Outcomes

On successful completion of the unit the student will be able to:

1. recognize and describe how vibrations are caused, characterized, and what their consequences are,
2. derive mathematical models of single and two-degree-of-freedom linear vibrating systems in free vibration and with various forms of excitation,
3. recognize and interpret the role of damping and natural frequencies in vibration transmission and in free and forced responses of the vibrating systems,
4. analyse and calculate modal and harmonic response characteristics of the vibrating systems with focus on their application in vibration control,
5. recognize, describe and analyse basic sources and mechanisms of aeroelastic problems in aerospace context,
6. interpret and report measured and simulated vibration data.

Teaching Information

The unit is centred around nominal 22 core lectures. A compulsory component of the unit is represented by one assessed laboratory investigation. Additionally, a series of these support and feedback activities is provided: revision lecture, invited industrial lecture, example class, and computer lab class on applications of Matlab in Vibrations 2.

Students are strongly advised to work with the provided example sheets. It is also recommended that the student study provided supplementary resources to expand and contextualize their knowledge.

Assessment Information

Two-hour written examination (80%; LO 1-5); coursework based on one compulsory laboratory investigation summarized in a single report (20%; LO 1&6).
