Assignment - Personal Case Study
Learning outcome 1: Describe the scientific features of different lubrication regimes and explain their significance in the context of the tribological performance of machine components
Learning outcome 2: Apply scientific and mechanical principles to analyse components to evaluate wear rates and friction coefficients using simple models for friction and wear
Learning outcome 3: Employ data, including extracting data pertinent to an unfamiliar problem, to synthesize innovative designs and/or critically evaluate the performance of journal bearings, tilted sliding pads and Hertzian contacts using calculator based and computer software based methods
Learning outcome 4: Apply mathematical models to critically review the reliability / failure of groups of machine elements and assess the limitations of a system
Learning outcome 5: Evaluate the impact of approaches to tribological elements of design and operational practice on the sustainability of products and/or engineering systems
The task
For this assignment you are asked to conduct an individual short "Personal Case Study" in which you analyse, in detail, the tribological performance (ie., lubrication, friction or wear) of a mechanism or moving contact of your own choice using a mathematical model. (Typically, this will be implemented in an Excel spreadsheet or your own code.
The main part of the work, ie. the tribological study, must not be completed using simulation software.) There are two steps:
(1) A brief (1 - 2 page) written plan describing your study, outlining the topic, specific aim (study question(s) to be addressed) and plan of analysis (including the list of equations to be used in your analysis placed in order), should be discussed, submitted and agreed with the Module Leader by 15th July 2021 at the very latest. (Email a copy of your plan to the Module Leader. This is a formative element, no marks are associated with this submission, it is done to ensure that you are working towards your marked assessment in an appropriate way.)
(2) For assessment, you are asked to present the results of this study in written form in as "technical paper" as well as making a "Three Minute Presentation (3MT) Powerpoint presentation about the work. Both of these elements will be assessed and marks will contribute to the module mark.
The technical paper and presentation must include:
• A brief literature survey.
• A detailed description of the mathematical model for the mechanism of lubrication, friction or wear you adopt.
• A quantitative example, that is a numerical analysis, of the effect of changes in design or operation of the device on the lubrication/friction/wear mechanism in application you have chosen. Consider several cases of design or operation and compare them.
• A discussion including a description and quantitative assessment of the ways to optimise a design approach to the device. (e.g., improve the lubrication conditions or reduce friction or wear).
• Technical conclusions.
This study is intended to allow you to investigate the tribological phenomena you study in class in more detail and to place them into the context of an engineering application. This work expects you to seek out and review research papers, technical data and reports on relevant topics. The task extends an opportunity for you to develop key skills in conveying technical information and knowledge.
