 SHE Level 4 SCQF Credit Points 20.00 ECTS Credit Points 10.00 Module Code MHH324749 Module Leader Martin MacDonald School School of Computing, Engineering and Built Environment Subject SCEBE - School Office Trimesters A (September start) B (January start)

### Summary of Content

The aim of this module is to provide an application of computer aided design to realistic solution of Engineering problems. Solution to the above involves the use of solid modeling mechanism and analysis tools. Areas covered include mechanism/linkage analysis, Sensitivity and optimization techniques/studies for a range of engineering systems and introduction to computational Fluid Dynamics (CFD).

### Syllabus

Geometric modeling of engineering systems as an assembly using commercially available software tools. Mechanism Analysis: Transfer and describe assembly, in terms of mass properties, cams, slots, connections materials, loads, drivers and boundary conditions. Sensitivity and optimization: Define a range of design variables for geometric and material properties for sensitivity studies for linear elastic, dynamic problems to establish initial parameters. Perform optimal solution using selected design variables for specified optimization goal and imposed design constraints such as displacement, stress, temperature and /or frequency. Computational Fluid Dynamics: Modeling and solution schemes are implemented to solve laminar and turbulent flow through ducts and over profiles.

### Learning Outcomes

On completion of this module the student should be able to: 1. Model an engineering system as an assembly and conduct mechanism analysis of the assembly to establish parameters such as acceleration, velocity, displacement and force. (AM1, AM3/AM4)2. Conduct global and local sensitivity studies and perform optimization study of selected engineering components. (AM1, AM3/AM4)3. Conduct fluid flow analysis involving laminar and turbulent flow. (AM1, AM3/AM4)

### Teaching / Learning Strategy

Practical use of an integrated modeling and manufacturing package is the learning strategy used for most of this module.
