Course Description

Noise and vibration of motor vehicles is gaining increasing importance in the automotive industry involving both vehicle manufacturers and component suppliers. While noise pollution legislation is driving down vehicle exterior noise, customers are becoming more discerning regarding noise and vibration inside the vehicle. In fact, noise and vibration levels are now considered as important quality parameters in vehicle design. This course aims to develop your appreciation for the sources and mechanisms of noise and vibration generation and transmission in motor vehicles. In addition, it aims to introduce you to design principles and palliative treatments to help meet noise and vibration targets.
In general, the course aims to introduce you to the noise and vibration of motor vehicles and the application of noise and vibration control principles to the design of quality automotive vehicles. You will develop an understanding of structure borne and airborne noise transmission and the physical mechanisms involved. More specifically, upon completion of this course you will be able to describe and identify the main sources of noise and vibration in vehicles, such as the engine, transmission, tyre/road interface and intake and exhaust systems. You will describe these sources individually and their respective contributions to overall interior/exterior design of the vehicle, resulting in better understanding of the role of trim, isolating mounts and structural/acoustic design in the reduction of noise and vibrations in the passenger compartment. You will use contemporary computational and experimental techniques to achieve these outcomes.

Please note that if you take this course for a bachelor honours program, your overall mark in this course will be one of the course marks that will be used to calculate the weighted average mark (WAM) that will determine your award level.

This applies to students who commence enrolment in a bachelor honours program from 1 January 2016 onwards. See the WAM information web page for more information.(http://www1.rmit.edu.au/browse;ID=eyj5c0mo77631)

Overview of Learning Activities

The course will provide you with the opportunity to learn through the following main learning activities:

a) Lectures, which will introduce you to the main theoretical concepts and methods. Note that lectures involve a significant component of practical demonstrations.
b) Tutorials, which aim to enable you to reflect on theory and apply main concepts through problem solving involving real-world and industry problems.
c) Assignments will give you a chance to apply theory to a realistic problem.
d) Laboratory Experiments, which will allow you to relate theory to practice through active experimentation about noise/vibration and components in a range of laboratory settings using state-of-the-art instrumentation.
e) Computer Laboratory, which will allow you to work in on noise and vibration control using CAE methods.


Overview of Learning Resources

A range of learning materials and resources will be available to students through the Online Learning System (Blackboard).
Assignments, Virtual Laboratory, Projects, Guides for the Laboratory experiments, selected Lecture Notes and Slides, Examples of relevant computer programs, etc. will be generally provided.
