My goal is to assess friction and wear of the various materials under various conditions (loads, speed, lubrication, materials).<br /><br />Aims<br />- Use Thrust washer test rig for the evaluation of various materials and lubricants<br />- Use of a profilometer to assess surface topography before and after wear testing<br />- Use friction load cell and data recorder to evaluate friction<br />- Apply tribological concepts to determine specific wear rates and friction of various materials tested under various conditions.<br /><br />Information<br />- Information regarding the use of Thrust Washer will be taken from website (http://bearings.globalspec.com/LearnMore/Mechanical_Components/Bearings_Bushings/Thrust_Washer)<br />- Information regarding the use of profilometry for wear assessment will be taken from the Taylor Hobson manual or website (http://www.taylor-hobson.com)<br />- Additional information will be found in the Tribological course and http://www.tribology-abc.com<br />- Edin E. Balić and Thierry A. Blanchet Wear, Vol. 259 (2005) PP 876-881.<br />- P. J. Kelly, R. D. Arnell, M. D. Hudson, A. E. J. Wilson and G.

If organised, this should not be a problem.<br /><br /><br /><br />Student signature: NOT ON WEB<br /><br /><br />Tutor signature: NOT ON WEB<br /><br /><br />Date: 30/10/06<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/5454554284700901947-7932934458110098589?l=thrustwasher.blogspot.com' alt='' /></div>Mundhir UFOhttp://www.blogger.com/profile/16040408902239768755noreply@blogger.com0
