EGB321 Dynamics of Machines

Unit Outline: Semester 1 2024, Gardens Point, Internal

Overview

Professional engineers have a "comprehensive, theory-based understanding of the underpinning natural and physical sciences and the engineering fundamentals applicable to the engineering discipline" (Engineers Australia Stage 1 Competency Standard for Professional Engineers). This engineering core unit introduces fundamental concepts of dynamics & vibration of machines in an engineering context. You will develop the ability to recognise and apply the developed theories and formulas to solve fundamental engineering problems involving position, velocity, acceleration and force and to solve more complex problems involving nonlinear equation of motion, free body diagram as an introduction to predicting the vibration behaviours of engineering systems. You will undertake laboratory work in groups to plan and conduct experiments to predict and analyze the behavior of physical systems and apply this theoretical dynamics knowledge into practice to design walkable robots. 

Learning Outcomes

On successful completion of this unit you will be able to:

1. Apply fundamental principles in dynamics to the analysis of machine component motion, at a developed level.
2. Solve problems in dynamics for the motion of mechanical components and mechanisms, at a developed level.
3. Communicate analysis and modelling in dynamics, of machines at a developed level.

Content

Learning Approaches

In this unit you can expect to experience the following timetabled activities:

• Formal lectures from experienced professional engineers and scientists that will activate your understanding of theories and principles, and model approaches to solving problems. You will have the opportunity to ask questions during these lectures.
• Tutorial classes that will give you the opportunity to work collaboratively with your peers to solve problems. These will be facilitated by tutors and will provide an opportunity to test your understanding and gain feedback on your work.
• Practical classes, in which you will collaboratively plan for and conduct experiments to give you hands on experience with the physical phenomena that you are learning about.
• To complement timetabled activities, you can expect to be provided with learning resources including videos and readings on a unit Canvas site that you can access flexibly to complete your learning in this unit. Success in this unit will require you to manage your time to ensure you have focused time each week (beyond timetabled activities).

At the beginning of the unit, you will be made aware of the ways in which you can ask questions or seek clarification from the Unit Coordinator and Tutors.

You are expected to:

• Engage with timetabled activities on campus and ask questions.
• Manage your time to engage with online resources outside of timetabled activities. These will be available on the unit Canvas site. You will receive regular email announcements regarding release of these resources.
• Engage with your peers in a learning community to practise problem solving and then work independently to complete your assessment tasks.
• Prepare for timetabled classes and activities and follow up on any work not completed.
• Complete assessment tasks by working consistently across the semester and meeting the due dates that are published via the unit Canvas site.

Feedback on Learning and Assessment

Unmarked Assessments
You will have the opportunity to practice and reflect on what you are learning with a range of unmarked assessment tasks throughout the semester, including quizzes, tutorial problems and practical laboratory experiments.

Assessment

Overview

As you progress through this unit, you will move between learning underpinning scientific theory and concepts regarding the dynamics of linkages & vibration of complex machine systems and using these theories in practical applications. You will be developing your capability to solve problems by looking at physical systems and diagnosing the appropriate theory and methods to predict behaviors, which is a key capability for professional engineering practice. The assessment for the unit is designed to assess your learning against the unit learning outcomes and includes problem-solving tasks (robot design using linkages), reporting on experimental work (vibration lab practice), and a final exam, which will test your capability to diagnose and solve problems in engineering science.

Assessment Tasks

Assessment: Robot Design and Report

Design and validate a 4bar linkage robot to demonstrate the working principles of a mechanical machine, and then justify the design using the theoretical knowledge from the lecture. To complete the task the student must use both the computer packages and advanced analytical techniques. In a written report, describe the design process, including:

• The abstraction and classification of the problem, modelling the task within the analytical frameworks introduced in the lectures/tutorials
• The design choices
• The analysis of the problem and the resulting solution

This is an assignment for the purposes of an extension.

Assessment: Prac Lab Report

You will be required to:
Questions (written) selected by the lecturer similar to the list of weekly assigned questions. The document must show evidence of the analytical process used to obtain the results.

Written report analysing the data collected during the practical sessions related vibrations. The reports must contain an explanation of the process you used to obtain the results and a discussion relating the theory to the obtained results. Format of the report must follow that you used in Dynamics. (Laboratory work will be in groups but assessed individually).

This is an assignment for the purposes of an extension.

Assessment: Examination (written)

You will apply the fundamental theory of kinematics, kinetics and vibration and the related advanced analytical techniques to solve problems. You will also explain theoretical concepts and analytical techniques regarding kinematics and kinetics of machine components and vibration answering open questions.

“If campus access is restricted at the time of the central examination period/due date, an alternative, which may be a timed online assessment, will be offered. Individual students whose circumstances prevent their attendance on campus will be provided with an alternative assessment approach.”

Academic Integrity

Students are expected to engage in learning and assessment at QUT with honesty, transparency and fairness. Maintaining academic integrity means upholding these principles and demonstrating valuable professional capabilities based on ethical foundations.

Failure to maintain academic integrity can take many forms. It includes cheating in examinations, plagiarism, self-plagiarism, collusion, and submitting an assessment item completed by another person (e.g. contract cheating). It can also include providing your assessment to another entity, such as to a person or website.

You are encouraged to make use of QUT’s learning support services, resources and tools to assure the academic integrity of your assessment. This includes the use of text matching software that may be available to assist with self-assessing your academic integrity as part of the assessment submission process.

Further details of QUT’s approach to academic integrity are outlined in the Academic integrity policy and the Student Code of Conduct. Breaching QUT’s Academic integrity policy is regarded as student misconduct and can lead to the imposition of penalties ranging from a grade reduction to exclusion from QUT.

Risk Assessment Statement

You will be informed of any requirements pertaining to a safe workplace. In lectures, tutorials and such, the information will include location of fire exits and meeting points in case of fire. If you do not follow legitimate instructions or endanger the safety of others or do not act in accordance with the requirements of the Workplace Health and Safety Act, you will be required to leave the session.

You will be required to undertake practical sessions in the laboratory under the supervision of members in the teaching team and technical staff. Prior to entry to a laboratory space you must complete the Undergraduate Health, Safety and Environment Induction (annual completion requirement). 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, lab coat, and safety glasses). The unit’s Canvas site will provide you with a copy of the risk assessment and will provide you with details on how to perform the laboratory tasks safely.
