Project Specification
NR7
Name of student: Mundhar Suhail Ali AL SHIBANI
Department of Technology – Beng (Hons) Mechanical Engineering
Project title - Thrust Washer
Project Tutor – Nathalie Renevier
Academic year – 2006 - 2007
Introduction
In my project, I will test various materials and lubricants using a well-known tribological thrust Washer test rig. My goal is to assess friction and wear of the various materials under various conditions (loads, speed, lubrication, materials).
Aims
- Use Thrust washer test rig for the evaluation of various materials and lubricants
- Use of a profilometer to assess surface topography before and after wear testing
- Use friction load cell and data recorder to evaluate friction
- Apply tribological concepts to determine specific wear rates and friction of various materials tested under various conditions.
Information
- Information regarding the use of Thrust Washer will be taken from website (http://bearings.globalspec.com/LearnMore/Mechanical_Components/Bearings_Bushings/Thrust_Washer)
- Information regarding the use of profilometry for wear assessment will be taken from the Taylor Hobson manual or website (http://www.taylor-hobson.com)
- Additional information will be found in the Tribological course and http://www.tribology-abc.com

Theory
Thrust Washer Friction
Achard Law Hertizien pressure contact
Specific Wear rate Project management
Excel software Lubrication regime
Design
- I will create a design of experiments that will take into account all the critical parameters (ie, load, speed, environment)
- Wear loss will be measured by 2 means (weight and profilometry), specific wear rate will be calculated using tribological equations and both methodologies will be compared.
Applications
- Test samples will need to be surface finished before use (no more than ½ day workshop technician time).
-
- Information on wear of materials measured during the project will recorded in a database.
- Health and safety hazards are only contained in the manipulation of lubricants, appropriate equipment will be provided.
Tests
- Data base will be created reporting best wear resistant materials and lower friction tested in various conditions.
- Excel model will be used to calculate wear rate and used to create the data.
Risks
During the project, I have identified that may be some problems will arise which could affect the whole process with regard to time allocation, so to attempe to anticipate and downsize the problem below is the list of possible problems,
a) Insufficient time management regarding resource availability
b) Equipment breakdown including the Thrust Washer or the Taylor Hobson surface measurement machine
c) Insufficient time management regarding lecturer availability
