TALAT lecture 2401: fatigue behaviour and analysis

This lecture explains why, when and where fatigue problems may arise and the special significance to aluminium as structural material. It is provided as a pdf document.

It also helps to understand the effects of material and loading parameters on fatigue; to appreciate the statistical nature of fatigue and its importance in data analysis, evaluation and use; shows how to estimate fatigue life under service conditions of time-dependent, variable amplitude loading; how to estimate stresses acting in notches and welds with conceptual approaches other than nominal stress; and provides qualitative and quantitative information on the classification of welded details and allow for more sophisticated design procedures. Background knowledge in materials engineering, design and fatigue is required.

TALAT lecture 2101.02: the product development process

This lecture provides a brief introduction to the product development process and systematic design. It is provided as a pdf document.

It aims at generating interest in and a common understanding of the product development process; informing about the basic principles and terminology used in connection with systematic design in order to facilitate the use of the four product design examples presented in this course (see TALAT lectures 2102.01, .02, .03 and .04). The lecture is recommended for those situations, where a brief, general background information about aluminium is needed as an introduction of other subject areas of aluminium application technologies. This lecture is part of the self- contained course “Aluminium in Product Development”, which is treated under TALAT lectures 2100.

Resources for an introduction to modelling

This website contains links to resources for an introduction to modelling for first year engineering undergraduate.

The resources here include the lecture hand out (zip file) which includes embedded tutorial questions, some powerpoints for structuring lectures , flash animations to step through modelling process for electrical circuits and a large data base of CAA developed on webct (here provided in zip files for quiz 1 and quiz 2). The files import into webct and self extracts. The lecture notes also contains a brief overview on usage for lecturing staff.

The main focus is on electrical and mechanical systems, but there is also some discussion of dc motors, fluids and heat as well as an introduction to time series modelling. The main emphasis is on why modelling is important and how to go about doing this from first principles (e.g. Kirchhoff’s laws, Newton’s Laws, etc.). Given the focus is on new students arriving at University, there is no attempt to develop models beyond second order.

These were developed at the University of Sheffield and authored by J. A. Rossiter from the Department of Automatic Control and Systems Engineering.

How to specify and choose a clutch

This is one of the SEED curriculum engineering design guides. SEED (Sharing Experience in Engineering Design) is an organisation of teachers of design in tertiary education.

You can use this guide together with manufacturers catalogues to specify and select a clutch that will meet your needs. If you are not very familiar with the standard types of clutch available from stock then review the sections on Uses of clutches and Types of clutch available from manufacturers. Reference should be made at every stage of the selection process to the Product Design Specification (PDS) for the system (all the relevant factors should be described in a well written PDS). The characteristics of clutches available “off the shelf” often may constrain the design of the system that requires the clutch so be prepared to change your design to match a manufacturer’s clutch. The guide also specifies the environment and the requirements for the clutch, how to choose a clutch, and a list of clutch suppliers.

Unit selection – electric motor

This is one of the SEED curriculum engineering design guides. SEED (Sharing Experience in Engineering Design) is an organisation of teachers of design in tertiary education.

The purpose of this guide is to enable the user to determine the attributes required of an electric motor to meet a specific power transmission need and then to select one from those offered by manufacturers. It has been compiled as part of a series, which covers typical elements of a system.

In this guide only conventional power transmission motors will be considered. This covers AC and DC motors between about 30 watts and 30 kilowatts. Other motors will be dealt with in other guides. The guide looks at the selection procedure, factors affecting motor selection, and motor selection and specification.

Unit selection – gearbox

This is one of the SEED curriculum engineering design guides. SEED (Sharing Experience in Engineering Design) is an organisation of teachers of design in tertiary education.

The purpose of this guide is to enable the user to determine the attributes required of a gearbox to meet a specific power transmission need and then to select an appropriate gearbox from those offered by manufacturers. It has been compiled as part of a series which covers typical elements of a system. It is not concerned with the detailed design of a gearbox which will be covered in other guides in this series. Before embarking on the selection procedure it is necessary to ensure that the need for a gearbox, has been carefully considered. The guides at higher levels in the Mechanical Power Transmission Series provide assistance in this process. The successful selection of a suitable gearbox is the result of matching the requirements of the power transmission system with one of the range of boxes offered by the manufacturers. Thus information about the system and information about available hardware is necessary.

The guide looks at the selection procedure, types of gearbox and their characteristics, general characteristics, factors affecting gearbox selection, and manufacturers.

How to choose a seal

This is one of the SEED curriculum engineering design guides. SEED (Sharing Experience in Engineering Design) is an organisation of teachers of design in tertiary education.

You can use this guide to determine what kind of a seal will meet your needs and then to select a seal from those offered by manufacturers. If you are not very familiar with the standard types of seal available from stock then review the section on standard seal types available from manufacturers. Reference should be made at every stage of the selection process to the Product Design Specification (PDS) for the system (all the relevant factors should be described in a well written PDS). The characteristics of seals available “off the shelf” often constrain the design of the system components that require the seal so be prepared to change their design to match a manufacturer’s seal.

The guides looks at how to: specify the environment and operating conditions, specify the performance of the seal, select the type of seal required, select the material for the seal, choose a seal from a manufacturer’s catalogue, review your choice of seal. There is also a list of seal manufacturers.
