MECH8416: Advanced Design and Analysis

Semester 1, 2020 [Normal day] - Camperdown/Darlington, Sydney

Overview

This UoS utilises assumed theoretical knowledge and skills to elucidate the stresses and strains that exit in the different categories of machine parts. It sets out to make the students familiar with the simplifications that are applied to arrive at the analytic expressions commonly used to analyse each individual categories parts. These simplifications usually begin by assuming that only particular types of loads are carried by teh parts in that category. The resulting analyses provide approximations to the actual stresses. It is possible to have different degrees of simplifications, requiring more or less work, giving better or poorer approximations. Should a part be used to carry loads that were not allowed for in the traditional method then some more appropriate method must be found or developed. An important aspect is to make the student practiced in a range of modern concepts, techniques and tools, and to be made aware of their strengths and limitations. This UoS teaches the student how to recognise where and how their theoretical skills can be applied to the practical situations that they may encounter in this field of design. Options may be provided in the choice of design assignments. Biomedical engineering and vehicle design problems may be provided as options to more general machine design problems.

Assignment 2: The second assignment examines the designs of a space 3D frame to meet a simplified but realistic application.
Assignment 3: The third assignment is devoted to the design of the gear set for a speed reducing gear box.
Assignment 4: The fourth assignment will deal with the design of a clutch or brake for a train, truck or car.

Detailed information for each assessment can be found on Canvas.

Assessment criteria

The University awards common result grades, set out in the Coursework Policy 2014 (Schedule 1).

As a general guide, a high distinction indicates work of an exceptional standard, a distinction a very high standard, a credit a good standard, and a pass an acceptable standard.

Result name	Mark range	Description
High distinction	85 - 100
Distinction	75 - 84
Credit	65 - 74
Pass	50 - 64
Fail	0 - 49	When you don’t meet the learning outcomes of the unit to a satisfactory standard.

For more information see sydney.edu.au/students/guide-to-grades.

For more information see guide to grades.

Late submission

In accordance with University policy, these penalties apply when written work is submitted after 11:59pm on the due date:

Deduction of 5% of the maximum mark for each calendar day after the due date.
After ten calendar days late, a mark of zero will be awarded.

Academic integrity

The Current Student website provides information on academic integrity and the resources available to all students. The University expects students and staff to act ethically and honestly and will treat all allegations of academic integrity breaches seriously.

We use similarity detection software to detect potential instances of plagiarism or other forms of academic integrity breach. If such matches indicate evidence of plagiarism or other forms of academic integrity breaches, your teacher is required to report your work for further investigation.

You may only use artificial intelligence and writing assistance tools in assessment tasks if you are permitted to by your unit coordinator, and if you do use them, you must also acknowledge this in your work, either in a footnote or an acknowledgement section.

Studiosity is permitted for postgraduate units unless otherwise indicated by the unit coordinator. The use of this service must be acknowledged in your submission.

Learning support

Simple extensions

If you encounter a problem submitting your work on time, you may be able to apply for an extension of five calendar days through a simple extension.  The application process will be different depending on the type of assessment and extensions cannot be granted for some assessment types like exams.

Special consideration

If exceptional circumstances mean you can’t complete an assessment, you need consideration for a longer period of time, or if you have essential commitments which impact your performance in an assessment, you may be eligible for special consideration or special arrangements.

Special consideration applications will not be affected by a simple extension application.

Using AI responsibly

Co-created with students, AI in Education includes lots of helpful examples of how students use generative AI tools to support their learning. It explains how generative AI works, the different tools available and how to use them responsibly and productively.

Learning outcomes

Learning outcomes are what students know, understand and are able to do on completion of a unit of study. They are aligned with the University's graduate qualities and are assessed as part of the curriculum.

Outcomes
Graduate qualities

At the completion of this unit, you should be able to:

LO1. consider the range and evolution of CAD systems to aid in the selection of systems for particular duties, for today and in the near future
LO2. use a modern kinematic and dynamic package that is integral with our solid modeler CAD system to simulate articulated machinery and determine joint loads between the parts
LO3. analyse a simple mechanical assembly, using the FEA package included in our CAD package to critically consider if the assembly can function as required and if the parts are of appropriate shapes
LO4. design and make a space frame to carry specified loads and meet dimensional and functional requirements, such that it may be compared with competing frames
LO5. select a type then design, a brake system for one of a range of applications, such as taxi, crane, metro train or competition car
LO6. design a bolted joint to carry shear loads
LO7. determine the appropriate parameters for a gear pair, and possibly a whole gear train, according to AGMA design guidelines by using the numeric optimising solver built into Excel, providing the means of arriving at the lightest or cheapest gear sets
LO8. apply modern fatigue life predictions in general to component parts
LO9. use a numerical solver to arrive at optimal design dimensions and material properties, provided the invention part of the design is completed and only the size and shape of the design has to be settled
LO10. calculate the parameters that define a matched pair of spur gears, leading to the selection of multiple gear pairs in gearboxes
LO11. apply considerations of geometrical and practical constraints in the design of parts and assemblies.
