Sample subject outline - Semester 2 2012

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

Rationale

The measurement and control of noise and vibration experienced in industry is an important area of
responsibility in mechanical engineering. This unit requires you to understand and apply basic theories in
order to model and predict noise and vibration. It will provide you with sufficient experience in
instrumentation, measurement and analysis of noise and vibration to apply these skills competently in
industry. It is located in third or fourth year to build on mechanical engineering skills developed in previous years and to further develop your problem solving and analytical skills for later project work and
instrumentation.

Aims

The aim of the unit is to develop your theoretical knowledge, practice and problem solving skills in
measurement and control of industrial noise and vibration in test (laboratory) and real world applications. It will lay the foundation for you to apply analytical skills to a final year project and to real engineering
problems in industry to appropriate standards.

Objectives

On completion of this unit you should be able to:
1. formulate and solve problems related to industrial noise and vibration,
2. measure and analyse noise and vibration according to relevant standards and criteria using appropriate computer software and programs,
prepare noise and vibration reports to appropriate technical and professional standards, using additional information from external sources to support your evidence.

Content

· Behaviour and analysis of sound waves
· Absorption and reflection
· Measuring noise and noise criteria
· Attenuation from barriers and screens
· Behaviour of sound in room
· Sound transmission through partitions
· Noise reduction due to enclosures
· Vibration generation and transmission
· Measuring vibration and analysis
· Measuring vibration and analysis
· Instrumentation and vibration condition monitoring
· Balancing of rotating machines
· Vibration damper and control

Approaches to Teaching and Learning

Teaching Mode: Hours per week: 4 (including 4 practicals)
Lecture: 2 hours
Tutorial: 1 hours
Practical sessions: 1 hour equivalent (4 across semester: 2 on noise; 2 on vibrations)
The unit includes weekly lectures and tutorials with scheduled practical sessions. The lecture will include
references to fundamental concepts and 'real life' engineering problems, interactive tutorials will provide
individual and team engagement with emphasis on learning by formulating and solving problems. Team
work participation in assignments will form part of the collaborative learning process and ongoing feedback will be provided to improve students understanding and application of the knowledge.
Practical sessions will improve the students learning through applying theory in practice in real contexts and consists of laboratory experiments and on-site measurement of 'real life' noise and vibration signals.
Computer analytical software will be introduced to assist student learning using professional skills and tools. Formative student evaluation of the unit will support learning through feedback and engagement to improve the unit.

Assessment

General Assessment Information
The assessment in this unit is designed for you to:
* problem solve key effects of mechanical noise and vibration in industry,
* conduct practical experiments to test and analyse results,
* report well supported findings using professional tools, standards and criteria.
Because of the emphasis on problem diagnosis and solving as well as application and analysis, the
assessment is weighted 40% for practical work and reporting and 60% for the final exam.To let you know how you are progressing throughout the unit, you will receive oral feedback during tutorial discussions throughout the semester. The written feedback you receive on your first Noise report in mid-semester will provide valuable guidance on issues you may need to address for the second Vibration practical reports due at the end of semester. Feedback to prepare for the exam will be provided in lectures
and tutorials throughout the semester.

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

Required:
* Compilation of notes on industrial noise and vibration, A.C. Tan
* QUT Blackboard web site for unit ENB 314
Recommended:
* W.T. Thomson (1993) Theory of vibration and applications, Chapman & Hall
* S.G. Kelly (1993) Fundamental of Mechanical Vibration, McGraw Hill

Risk assessment statement

You will undertake lectures and tutorials in the traditional classrooms and lecture theatres. As such, there
are no extraordinary workplace health and safety issues associated with these components of the unit.
You will be required to undertake practical sessions in the laboratory under the supervision of the lecturer
and technical staff of the School. In any laboratory practicals you will be advised of requirements of safe and responsible behaviour and will be required to wear appropriate protective items (e.g. closed shoes or steel capped shoes). You will undergo a health and safety induction before the commencement of the practical sessions 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.
