### Course Aims

The aims of this course are to:

■ provide an introduction to theories of nonlinear dynamics with practical applications to problems in engineering;

■ introduce concepts of nonlinear vibration analysis;

■ provide the analytical and numerical tools to solve complex dynamical systems;

■ establish an advanced vectorial description of the kinematics of a rigid body for generalised motion with applications to multiple link machines and rotating bodies.

### Intended Learning Outcomes of Course

By the end of this course each student will be able to:

■ apply rigorously the Newton-Euler equations to a rigid rotor for purposes of machine design;

■ identify sources and categories of nonlinearity in models of vibrating systems;

■ explain the limitation of the linear modal analysis and describe some techniques to overcome such limitations;

■ set up reduced order models which lend themselves to the analysis of complex dynamical systems;

■ analyse the response of a nonlinear system and recognise the type of nonlinearity from the characteristics of the response;

■ use the most common numerical and analytical tools for the study of dynamical systems;

■ discuss issues of stability analysis in certain dynamical systems encountered in engineering;

■ explain the principles of signal analysis and processing in order to understand the operation of digital spectrum analysers;

■ use sufficient vector algebra to model kinematic systems relating to real engineering machines to a significant degree of complexity;

■ evaluate complete vector analytical solutions to multiple link systems and rotating links with slider couplings.

### Minimum Requirement for Award of Credits

Students must attend the degree examination and submit at least 75% by weight of the other components of the course's summative assessment.

Students should attend at least 75% of the timetabled classes of the course.

Note that these are minimum requirements: good students will achieve far higher participation/submission rates.  Any student who misses an assessment or a significant number of classes because of illness or other good cause should report this by completing a MyCampus absence report.
