ENEX13005 - Machine Design and Vibrations

General Information

Unit Synopsis

This unit will introduce you to the fundamental synthesis of mechanisms and machines. You will start by carrying out analysis of linkages in terms of their transmission angles, toggle positions and mobility for a certain mechanism. The kinematic analysis of any mechanism requires an acceleration analysis that depends on its position and velocity. You will be able to carry out this position, velocity, and acceleration analysis of these mechanisms (kinematic systems) using analytical equations and graphical methods. This unit will enable you to work on 3D CAD modelling and computer simulation of various mechanisms or machines. You will move on to kinetic analysis of systems thereby discussing static and dynamic balancing of rotating masses. After learning concepts of dynamics, you will study vibrations (free and forced) of single and multi-degree of freedom systems and will be able to carry out analysis of such systems using force and energy methods. Students enrolled online are required to attend a compulsory Residential School and have access to a computer and make frequent use of the internet.

Attendance Requirements

All on-campus students are expected to attend scheduled classes - in some units, these classes are identified as a mandatory (pass/fail) component and attendance is compulsory. International students, on a student visa, must maintain a full time study load and meet both attendance and academic progress requirements in each study period (satisfactory attendance for International students is defined as maintaining at least an 80% attendance record).

Assessment Overview

Recommended Student Time Commitment

Each 6-credit Undergraduate unit at CQUniversity requires an overall time commitment of an average of 12.5 hours of study per week, making a total of 150 hours for the unit.

Assessment Tasks

Assessment Task Weighting
1. Online Quiz(zes) 20%
2. Written Assessment 15%
3. Written Assessment 20%
4. Practical Assessment 15%
5. Portfolio 30%

This is a graded unit: your overall grade will be calculated from the marks or grades for each assessment task, based on the relative weightings shown in the table above. You must obtain an overall mark for the unit of at least 50%, or an overall grade of ‘pass’ in order to pass the unit. If any ‘pass/fail’ tasks are shown in the table above they must also be completed successfully (‘pass’ grade). You must also meet any minimum mark requirements specified for a particular assessment task, as detailed in the ‘assessment task’ section (note that in some instances, the minimum mark for a task may be greater than 50%).

Feedback, Recommendations and Responses

Every unit is reviewed for enhancement each year. At the most recent review, the following staff and student feedback items were identified and recommendations were made.

Source: SUTE unit comments report
Feedback
Students complimented the delivery of live lectures in which students were able to communicate with the unit coordinator.
Recommendation
The unit coordinator should continue to deliver live lectures for better engagement and learning experiences.
Action Taken
The unit coordinator delivered all lecturers live through Zoom and high-achieving students continuously attended these lectures.
Source: Student email and chat messages through Microsoft Teams
Feedback
Students complimented useful self-learning resources for Dynamic Simulation and the responsive behaviour of the unit coordinator.
Recommendation
The unit coordinator will also inform students of an additional communication channel which is Microsoft Teams. Through this platform, students can send casual messages instead of formal emails to consult the unit coordinator.
Action Taken
In Progress
Unit learning Outcomes

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

  1. Apply key concepts of kinetics and kinematics to analyse machine design and synthesis
  2. Use analytical and graphical techniques to carry out position, velocity, and acceleration analysis
  3. Apply concepts of dynamics in balancing of rotating components
  4. Analyse vibrations in single and multiple degree of freedom systems
  5. Communicate professionally using relevant technical terminology, symbols, and diagrams and effectively document calculations and solutions
  6. Work autonomously and as a team member to analyse problems and present solutions.

Learning outcomes will be linked to Engineers Australia stage 1 competency standards for Professional Engineers.
