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 in distance mode 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. Written Assessment 20%
2. Written Assessment 20%
3. Practical Assessment 20%
4. Portfolio 40%

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: Unit Evaluation
Feedback
The students liked the way its Moodle site was designed, which helped them sort back through the resources for particular information.
Recommendation
The Unit Coordinator will strive to improve further.
Action Taken
Nil.
Source: Unit Evaluation
Feedback
The students pointed out the final project could improve with clear explanations and requirements.
Recommendation
It was firstly designed to give an open-ended task. However, the Unit Coordinator will add more specific requirements and assessment criteria for each design task.
Action Taken
Nil.
Source: Unit Evaluation
Feedback
The students suggested the vibration part and its labs could improve.
Recommendation
The Unit Coordinator and lecturer will ensure the relevance of the content to the learning outcomes and ensure the lab equipment is error free.
Action Taken
Nil.
Source: Unit Evaluation & Self-observation
Feedback
The students felt over-stressed towards the end of the term due to the assessment items being positioned in the later weeks.
Recommendation
From the next offering, the vibration part will be delivered first, and then followed by the rest. This will ensure a fair distribution of study loads throughout the term.
Action Taken
Nil.
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.
