The course is designed to teach basic vibration phenomena and properties of single and multi degree of freedom discrete systems. This course also provides introduction to aeroelastic phenomena in aerospace context.
On successful completion of the unit the student will be able to:
• understand how vibration is caused, how it is measured, and what its consequences are, • be able to model and study single degree of freedom mass-spring-damper systems, both in free vibration and with various forms of excitation, • have understanding of natural frequencies and how these relate to free and forced vibration of single-degree-of-freedom systems, together with vibration transmission, • understand multi-degree of freedom systems in free and forced vibration and how to apply numerical methods of solution, • understand the basic sources of aeroelastic problems in aerospace context.
23 lectures (2 lectures per week), 3 hours experimental lab, 2 hours computer lab
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 80% for examination and 20% for torsional vibration absorber lab work.
