Overview

This unit provides students with a deep understanding of mechanical vibrations and their impact on the performance, functionality, and integrity of engineering systems. Through this course, students will develop the ability to analyze and resolve vibration-related challenges in a variety of real-world applications. The unit equips students with both the theoretical knowledge and practical skills necessary for addressing vibration issues, emphasizing problem-solving and critical thinking.

Students will gain proficiency in applying vibration analysis techniques to mechanical systems, enhancing their competence in identifying, measuring, and mitigating vibration problems. They will also develop hands-on experience through projects that integrate theoretical learning with practical applications, reinforcing their ability to design, analyze, and optimize systems for vibration performance and reliability.

Learning Outcomes

On successful completion of this unit, students will be able to:

Map and articulate the fundamental concepts of mechanical vibrations and justify their application in a variety of engineering design contexts;
Measure, interpret, and evaluate the key vibration characteristics of structures, machines and vehicles using experimental and analytical techniques;
Construct numerical models of vibratory systems such that they can be used to predict and enhance performance;
Compute and predict the vibration behaviour of complex mechanical systems (including two and multi degree-of-freedom) using vibration theory;
Analyse the vibration behaviour of structures and machines taking into account economic, industrial, human and environmental considerations; and
Present technical findings effectively through accurate, clear, and professional engineering reports for varied audiences.

Assessment

For Melbourne campuses

The mid-semester and final examinations are largely based on the work undertaken for the reports.

Assessment type: Report | Grade: 30%

Project-based report – Computational modelling and Analysis (2800 words) (Group)

Assessment type: Test | Grade: 70%

Two in-class invigilated tests. (35% each, 90 minutes each)

Report: Authenticity is ensured through milestone submissions, facilitator feedback, and verification of individual contributions within group documentation. Explicit evaluation of individual contributions further supports the secure assessment and assurance of each student’s achievement of learning outcomes. This task requires students to collaboratively develop and document analytical and experimental investigations of vibration behaviour in engineering systems. Each report demonstrates application of theory, computational modelling, and interpretation of data in line with professional reporting standards.

Test: Conducted under supervised, invigilated conditions verifying student understanding and capability. The tests assess students’ mastery of vibration theory, modelling, and problem-solving. These tests also evaluate analytical reasoning, design application, and understanding of vibration control and measurement across single and multi-degree-of-freedom systems.
