Clutch friction material screening using UMT TriboLab

Smooth clutch operation in automatic transmissions is strongly tied to the velocity dependence of the coefficient of friction (COF). Full-scale clutch tests, such as the JASO M348 or any other OEM-specific test protocol run on the SAE No. 2 Friction Test Machine, are typically used to obtain friction data, but these tests are both expensive and time consuming. In this application note from Bruker, explore the benefits of this process using the Bruker UMT TriboLab™ benchtop tester.
