Sample subject outline - Semester 2 2013

Note: Subject outlines often change before the semester begins. Below is a sample outline.

Rationale

After studying Fundamentals of Mechanical Design and Design of Machine Elements, it is important to learn the principles of design of machinery for specific application, machine element optimisation, how to provide equipment reliability and maintenance, take into account the role of styling, ergonomics and intellectual property protection as well as engineering ethics. This unit is located in the second semester of third year, to enable you to complete a systematic study of machine design with a comprehensive understanding of all factors influencing machinery performance.

Aims

After studying Fundamentals of Mechanical Design and Design of Machine Elements, it is important to learn the principles of design of machinery for specific application, machine element optimisation, how to provide equipment reliability and maintenance, take into account the role of styling, ergonomics and intellectual property protection as well as engineering ethics. This unit is located in the second semester of third year, to enable you to complete a systematic study of machine design with a comprehensive understanding of all factors influencing machinery performance.

Objectives

On completion of this unit you should be able to:

1. Design and optimise machine components to achieve desired function at affordable cost.
2. Select maintenance, lubrication and machine condition monitoring systems based on fundamentals of friction, wear and lubrication.
3. Take measures to improve equipment reliability at the design stage.
4. Carry out analysis of risks and hazards associated with particular equipment.
5. Communicate design information through teamwork, report writing and specialised software packages.

Content

1. Design of equipment for specific application (conveyors, heavy machinery, pressure vessels, food processing and pharmaceutical equipment).
2. Fundamentals of friction and wear.
3. Optimisation in design.
4. Design for reliability. The use of different methods for analysis and prediction of machinery failure (Anticipatory Failure Determination, fracture mechanics). Risk analysis. Maintenance systems.
5. Machine condition monitoring.
6. Styling and ergonomics in design.
7. OH&S, Environmental protection.
8. Intellectual property, Quality assurance in design, Engineering ethics.
9. Lubrication project.

Approaches to Teaching and Learning

Hours per week: 4
Lecture: 2
Tutorial: 2

Formal lecture sessions will cover the theory and illustrate some practical applications of design of machines for special application. Additional learning will be achieved by reading the course notes, reference material and working with specialised software packages. Individual and group Tutorial exercises will give you practice in machine element design and optimisation. Worked solutions will be made available progressively during tutorials and on the Blackboard-site. Some classes will be conducted in the Design Laboratory with real equipment. Assessment will simulate real-life design problems and in many cases will require communication with other students. Assessment is designed to strengthen understanding of the basic concepts and techniques and to develop skills in definition and solution of real design problems. Class work will be supplemented with self-study using Blackboard-site where different teaching and learning resources are available online.

An essential part of the unit is a Lubrication project. This project continues from the first part of the gearbox design project you carried out in ENB316. In this unit you will carry out the second part of the project developing lubricating system for that gearbox. You will also suggest a maintenance and condition monitoring systems to ensure reliable performance of the gearbox.

Assessment

Assessment includes written problem solving tasks, a lubrication project report and final examination. These assessments are designed to further develop your professional engineering capabilities in teamwork and self management as well as your specific design skills.You will receive ongoing feedback throughout the semester through peer, team and tutor discussions in and outside class. You will also have the opportunity to receive feedback through written comments on your written assignments and project report. Oral feedback will be given after marking of each written assessment task with analysis of typical errors.

Assessment name: Problem Solving Task
Description: Task 1. Pressure vessel design.
Using pressure vessel design code you will design a tank to withstand an internal pressure and external loads.

Task 2. Optimisation of a shaft.
You will carry out an optimisation task such as minimisation of a shaft weight.

Academic Honesty

QUT is committed to maintaining high academic standards to protect the value of its qualifications. To assist you in assuring the academic integrity of your assessment you are encouraged to make use of the support materials and services available to help you consider and check your assessment items. Important information about the university's approach to academic integrity of assessment is on your unit Blackboard site.

A breach of academic integrity is regarded as Student Misconduct and can lead to the imposition of penalties.

Resource materials

Risk assessment statement

You will undertake lectures, tutorials and solid modelling classes in traditional classrooms and lecture theatres. As such, there are no extraordinary workplace health and safety issues associated with these components of the unit.

The lab sessions will be carried out in the Design Laboratory where enclosed foot ware is required (students provide themselves).

You will undergo a health and safety induction before the commencement of the academic year and will be issued with a safety induction card. If you do not have a safety induction card you will be denied access to laboratories.

Disclaimer - Offer of some units is subject to viability, and information in these Unit Outlines is subject to change prior to commencement of semester.
