Unit aim

Provides students with the fundamental theory of mechanical design and how to apply this in designing and analysing a wide range of machine components. Students will gain an understanding of the basic and advanced elements used in machine design. These include the characteristics of gears, bearings, shafts, keys, fasteners, weldments, springs, brakes and clutches, and flexible elements. It also provides analytical and case-based knowledge to make machines as integrated systems of machine elements. 

Unit content

Design, manufacture and assembly of basic machine elements  

Materials  

Machine frames   

Welded, adhesive and bolted joints, fasteners  

Stepped shafts  

Rolling element bearings  

Gear mechanics and manufacture  

Design for strength  

Design for other mechanical failure modes including fatigue, stress concentration  

Safety, ergonomics and standards

Learning outcomes

Unit Learning Outcomes express learning achievement in terms of what a student should know, understand and be able to do on completion of a unit. These outcomes are aligned with the graduate attributes. The unit learning outcomes and graduate attributes are also the basis of evaluating prior learning.

On completion of this unit, students should be able to:
1 design typical machine components and joints against possible modes of failure, including yield, fracture and fatigue
2 apply formal procedures of engineering design and the methods for choosing between competing alternatives, and develop skills in recording design calculations and reasoning in a workbook
3 demonstrate an understanding of safety issues, risk management and legal responsibility in engineering design
4 conduct and document design work as a team using CAD software package.
