SUMMARY

The discussion focuses on calculating the friction coefficient for racquet grip design using heat measurement techniques. The user plans to rub various grips for a set time and then utilize a heat sensor gun to measure the resulting temperature. Key challenges include the lack of specific material knowledge and the influence of factors such as heat capacity, heat transfer coefficient, and emissivity on the accuracy of the results. Traditional methods, like the block and ramp experiment, are questioned for their applicability in this context.

PREREQUISITES
  • Understanding of heat transfer principles
  • Familiarity with friction coefficient calculations
  • Knowledge of materials science related to grip materials
  • Experience with thermal measurement tools, specifically heat sensor guns
NEXT STEPS
  • Research the formula for calculating friction coefficients from heat measurements
  • Explore the impact of heat capacity and emissivity on thermal readings
  • Investigate traditional friction coefficient experiments, including block and ramp methods
  • Learn about the properties of common racquet grip materials
USEFUL FOR

This discussion is beneficial for materials scientists, sports equipment designers, and engineering students focused on product development and performance optimization in sports gear.

For my final year project at uni, I am designing a new racquet grip. Past of investigating current products, I am going to test the friction properties of current grips. My plan is to rub a number of grips for a set time and then, using a heat sensor gun, measure the grips heat.

My question is, what formula(s) should I use to take this heat value and calculate a meaningful friction value? It is very likely i won't know the specific materials of the grips tested

That seems like an experiment with a lot of opportunity for error, heat capacity, heat transfer coefficient, emissivity etc will all affect you results for the worse.
Why can't you use the traditional friction coefficient experiment? (ie a block & ramp)
