Subject Description

Unit 1, Computational Mechanics: Upon completion students will be able to formulate algorithms into working computer programs to solve engineering problems, and be aware of numerical errors inherent in many computational schemes. Topics covered include: fundamentals of numerical modelling; approximation and errors; roots of equations; numerical solution of linear algebraic equations; curve fitting and splines; interpolation and extrapolation; numerical differentiation and integration; pre- and post-computational analysis; graphical representation of results.

Unit 2, Electro-Mechanical Machine Behaviour: Upon completion students should; be familiar with the concepts and terminology of electrical power engineering; be able to describe the construction of common electrical and mechanical power sources; understand the operating characteristics of common electrical and mechanical devices used for motive power; be able to construct time and frequency - domain models of simple electrical, mechanical, pneumatic and hydraulic engineering components and systems; be able to compute time-and frequency-domain responses of linear dynamical systems. Topics covered include: DC and AC power supplies and distribution systems; inverters, transformers and rectifiers; principles and operation of single and multi-phase a. c. machines, induction motors, and DC machines; solid-state control of machines, principles and operation of electro- hydraulic and electro-pneumatic servo valves and actuators, System modelling; unified approach to modelling electrical, mechanical and thermal systems, block diagrams, transfer function and state-space representations, computation of transient and steady-state time responses and harmonic frequency responses; use of Matlab for system response calculations.

Assessment
