Subject Description

Unit 1, Computational Mechanics: Upon completion students will be able to formulate algorithms into working computer programs in C language 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

Two examination not exceeding two hours each; tutorial tests and assignments not exceeding 50 pages equivalent. Students will be notified of the weighting of assessment components at the beginning of semester.
