Paris Transport Authority (RATP) has teamed with Wabtec Corp. to test “Green Friction” technology for brakes in an aim to improve tunnel air quality. Wabtec says Green Friction reduces micro-particle ...

A bright orange truck made a few passes along Munger Shaw Road on Friday. It’s called SCRIM, and it’s a road survey machine that tests friction of pavement and surfaces. SCRIM stands for Sideway force ...

The functional lifetime of a wet clutch can be characterized using wear characteristics such as velocity dependence of the coefficient of friction (COF) and friction curves. Current market trends ...

In automatic transmissions a smooth clutch operation is related to the velocity dependence of the coefficient of friction (COF). Although JASO M348 and other full-scale clutch tests, or other ...

Friction is the enemy of all things mechanical, and without regular maintenance, machinery service life becomes severely reduced until, ultimately, the machines cease to function. Anyone who owns a ...

MxV RAIL R&D, RAILWAY AGE MARCH 2022 ISSUE: MxV Rail (formerly TTCI) conducted a series of full-scale wheel/rail (W/R) rolling contact tests using its Rolling Contact Fatigue Simulator (RCFS) to ...

Friction may not be the first problem we think of afflicting medical device design, but it is a real issue for many single-use medical devices like syringes, injection pens, and auto-injectors.

An expert offers a primer on popular medical device coatings and their applications. Kevin Guenther A catheter with a lubricious coating. In the world of low friction, lubricious coatings for medical ...
