Brief Handbook Description: 1. This UoS utilises assumed theoretical knowledge and skills to elucidate the stresses and strains that exit in the different categories of machine parts. It sets out to make the students familiar with the simplifications that are applied to arrive at the analytic expressions commonly used to analyse each individual categories parts. These simplifications usually begin by assuming that only particular types of loads are carried by teh parts in that category. The resulting analyses provide approximations to the actual stresses. It is possible to have different degrees of simplifications, requiring more or less work, giving better or poorer approximations. Should a part be used to carry loads that were not allowed for in the traditional method then some more appropriate method must be found or developed. An important aspect is to make the student practiced in a range of modern concepts, techniques and tools, and to be made aware of their strengths and limitations.

2. This UoS teaches the student how to recognise where and how their theoretical skills can be applied to the practical situations that they may encounter in this field of design.

3. Options may be provided in the choice of design assignments. Biomedical engineering and vehicle design problems may be provided as options to more general machine design problems.

Attributes listed here represent the key course goals (see Course Map tab) designated for this unit. The list below describes how these attributes are developed through practice in the unit. See Learning Outcomes and Assessment tabs for details of how these attributes are assessed.

Attribute Development Method Attribute Developed
Projects require selection of appropriate maths tools to support engineering analysis and design. (1) Maths/ Science Methods and Tools (Level 4)
Identify methods of analysis for the most common categories of machine components (2) Engineering/ IT Specialisation (Level 4)

Ability to work in groups and manage the work load realistically according to abilities. (7) Project and Team Skills (Level 2)

For explanation of attributes and levels see Engineering & IT Graduate Outcomes Table 2018.

Learning outcomes are the key abilities and knowledge that will be assessed in this unit. They are listed according to the course goal supported by each. See Assessment Tab for details how each outcome is assessed.

(7) Project and Team Skills (Level 2)
1. Ability to work in groups in team projects to achieve an increasingly complete solution to the design requirements
(4) Design (Level 4)
2. To apply modern fatigue life predictions in general to component parts.
3. Consider the range and evolution of CAD systems to aid in the selection of systems for particular duties, for today and in the near future.
4. Use a modern kinematic and dynamic package that is integral with our solid modeler CAD system to simulate articulated machinery and determine joint loads between the parts.
(2) Engineering/ IT Specialisation (Level 4)
5. Calculate weld thickness for a nominated joint outline, subjected to combined loads.Design a bolted joint to carry shear loads.
6. Design a space frame to carry specified loads and meet dimensional and functional requirements. Make a model of such a frame so that it may be compared with competing frames.
7. Consider the properties strengths and weaknesses of hydrodynamic bearings to lead to proper selection and maintenance.
8. Design or select a coupling that has the appropriate attributes with respect to power and misalignments.
(1) Maths/ Science Methods and Tools (Level 4)
9. Calculate the parameters that define a matched pair of spur gears, leading to the selection of multiple gear pairs in gearboxes.
10. Use a numerical solver to arrive at optimal design dimensions and material properties, provided the invention part of the design is completed and only the size and shape of the design has to be settled.

Assessment Description: Assignment: Four assignments, at three weeks intervals, that require typed reports with graphs and spreadsheet included. The assignments will be of equal value.

For each assignment students will be guided in detail as to what is required to achieve a pass grade. The advice will be less specific with respect to achieving a Credit or higher grade and they will be encouraged to extend their knowledge and if possible arrive at creative solutions.
Assessment Feedback: When the assignments are marked and returned, the coordinator will discuss in a following lecture the range of solutions proffered, those that followed unadvisable paths, those that were rigorous in their analysis, as well as those that were inventive and shed novel light of possible solutions.
Grading:
