Kinetic Friction Coefficient Measured in Tribotesting: Influence of Frictional Vibration
Using a novel anti-vibration tribometer with a yaw angle misalignment, Kado et al. (Trans. Jpn. Soc. Mech. Eng. C79: 2635—2643, 2013) have recently shown experimentally that frictional vibration in tribotesting causes considerable error, e.g., a 35% underestimation of the kinetic friction...

Using a novel anti-vibration tribometer with a yaw angle misalignment, Kado et al. (Trans. Jpn. Soc. Mech. Eng.
