  1. Friction Wear Tester Voice of the Engineer Chris Williams Harrison Sprague Ben Wolfe Eric Kutil Noah Barker-Eldon R14600 Customer: Dr. Iglesias Guide: Gary Werth 4/9/2014

  2. Agenda • Brief Overview • Functional Decomposition • Concept Generation • Engineering Requirements and Feasibility

  3. Project Overview • Friction tester for Dr. Iglesias • Used by herself and students for research • Establishes friction test capability in a new KGCOE lab http://www.phoenix-tribology.com/cat/at2/leaflet/te88.htm Fig 1: Example of linear reciprocating friction tester from ASTM G133-05

  4. Benchmarking • Quote from Phoenix Tribology • Stroke up to 25mm @ 2Hz, 50mm @ 1Hz • Max temperature 400deg C • We need 10mm @ 10Hz and 500deg C

  5. Functional Decomposition Run a friction test Control Test Operation Linearly Reciprocate Contact Point Adjust Duration Automatic Shutoff Manual Shutoff Apply Normal Force Heat Sample Transfers Data Hold Contact Specimen Ramp Temperature Maintain Temperature Sends Data to Labview Sends Commands to Tester Secure contact specimen Accomodate ball or pin contact Hold Bottom Specimen Shut off after specified time Manual Shut Off Button Fail Safe shutoff Secure Specimen Accommodate various Geometries Measures Temperature Measures Friction Force Measures Test Duration send Operating Frequency to tester send test duration to tester

  6. House of Quality Matrix

  7. Concept Generation A4, B3, C1, D3 A3, B2, C3, D1 A2, B1, C1, D2 A1, B1, C2, D2 A4, B1, C2, D3 Electric Heating Element Screws

  8. Function-Heat Sample Possible Solutions • Electricity • Flame • Steam

  9. Function-Hold Specimen Possible Solutions • Magnets • Clamps • Screws

  10. Function-Linearly Reciprocate Specimen Possible solutions • Fluid Power • Motor • Magnets • Disk and arm

  11. Function-Apply Normal Force Possible solutions • Screws • Weights • Hydraulics/pneumatics • Springs

  12. Function-Hold Contact Possible Solutions • purchase holder • make holder

  13. Function-Transfer Data Possible Solutions • thermocouple • strain gauge • PC • DAQ software • DAQ hardware • stopwatch

  14. Function-Control Test Operation Possible Solutions • Manual controls • Software controlled

  15. Areas of Uncertainty • Minimum-Ideal metrics unconfirmed with Dr. Iglesias • Cost of data acquisition hardware/software • Team size and expertise • Change in scope of project if a tester is purchased

  16. Next Steps • Meet with Dr. Iglesias to confirm metrics • Research costs of DAQ systems • Continue Feasibility Analysis
