Project Background

● Tests the wear and friction of materials● Design a reciprocating sliding contact friction test rig

o Ball-on-plate

FRICTION TESTER PROJECT

TWO TEAM COLLABORATIVE

BUILD

Group A Armature

SubsystemP15660

Group B Reciprocation

SubsystemP15661

Stakeholders

Dr. Iglesias Victoria● Primary stakeholder, sponsor and customer

Other important stakeholders● Friction tester reciprocating team (P15661)!

o Communication between teams is key for success

● Our own team (P15660)!o Succeding is in our best interest

● Research students using her labo Will be running experiments using test rigs

BenchmarkingRotating Friction Tester Located in Dr.

Iglesias’s Lab

Pros Cons

-Precision weights applied in vertical to contact point-Counterbalanced-Adjustable in X -Able to swing out for easy of use

-Needs XYZ Adjustability-Strain gauge works for rotating specimen scenarios only-Not easy to use

Most importantly, Dr. Iglesias wants TWO independent friction testers!!!

Problem Statement & Project Deliverables Current State:● The reciprocating friction testers are too expensive, or not the current

testing application

Desired State:● Fully functional reciprocating friction tester by the end of MSDII!

Project Goals:● Design and build an armature which will be attached to the reciprocating

base made by P15561 team

Constraints:● The armature must provide constant & accurate vertical Normal Force

o Weight of armature can’t affect normal force● Single point contact force variable from 0N to 20N● All data obtained must be stored and displayed● Budget of $1500, $2500 shared between both teams

Use Scenario

Customer Needs and Wants

Working reciprocating sliding contact friction test rig to be used in Dr. Iglesias’s lab by MSDII

Design and build an armature to be combined with reciprocating base:● $1500 budget (negotiable between teams)● Apply a vertical normal force up to 20N● Incorporate a zero force load release● Easy to use (clean, adjust, run test, etc.) ● Translate in the XYZ planes

Project Plan

Risk Management

Team Norms and Values● Punctual

○ Arrive at scheduled meetings on time

● Thorough○ Perform tasks thoroughly and completely○ Seek assistance in a timely manner

● Accurate○ Work is documented and easy to follow

● Professional and Ethical○ Give credit where it is due, be honest

● Conflict Resolution○ 1 on 1○ As a team○ Guide intervention

Problems Encountered and Lessons Learned● Same strengths from same discipline - Be able to adapt and learn

● Take charge in the interview - don’t let the conversation topic stray from the question that was asked

● If customer gives contradictory answers, verify which is correct if there is a correct answer

● House of Quality

● Project Planning

● Stay ahead and dont fall behind on tasks

Action Items● Establish interface requirements for LabView

o EEs

● Get in contact with rotating disk tester research studento Experienced with operating test rigso Can offer advice for ease of use

● Verify the roles of each team in the testing process (ie, who determines interface location? who is responsible for data acquisition, etc.)
