Friction testing device
Friction testing device
(OP)
Hey all,
Do you guys ever come in contact with friction measurements for solid-solid body contacts and if so what type of equipment or methods do you use?

RE: Friction testing device
I also have seen devices that use two force cells - one vertical and one horizontal, and they are used to measure normal force and lateral force to move one solid with respect to the second solid.
Lastly, there are rotational devices (used mainly for threaded fastener joints) that measure input torque and reaction torque to calculate friction coefficient.

RE: Friction testing device
Can you elaborate on the machine that uses two load cells or where one can find information about it...?

to your moving solid. Pull the fish scale and record the force F to initiate movement. The friction coefficient then is the ratio of F/N.
You can make the system much more accurate, etc. by using a universal testing machine (aka, tensile tester) to apply aand record a force, then use another force system to record the lateral force.
