Description including Unit Aims

The Vibrations course is designed to teach basic vibration phenomena, such as how vibration is caused, how it is measured, and what its consequences are. The single degree of freedom mass-spring-damper system is analysed, both in free vibration and with various forms of excitation. The importance of resonance and forced transmission is stressed. Students should gain an understanding of natural frequencies and how these relate to free and forced vibration, together with vibration transmission. They will also learn about multi-degree of freedom systems in free and forced vibration and how to apply numerical methods of solution. The laboratory class illustrates aspects of the course, especially resonance and damping and the behaviour of systems with two degrees of freedom.

Intended Learning Outcomes

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

  • understanding natural frequencies and how these relate to free and forced vibration, together with vibration transmission;
  • understand multi-degree of freedom systems in free and forced vibration and how to apply numerical methods of solution.

Teaching Information

  • 24 Lectures
  • 1 x 2 Hour Lab

Assessment Information

There is a 2-hour written examination in the summer (3 questions from 4). Marks for laboratory work are incorporated into the end of year unit assessment. The weighting is 90% for examination and 10% for lab work.
