Increasing friction of tread rubber under lubrication by adjusting groove shape to control fluid flow
This study aimed to develop a high-friction tread design by utilizing fluid flow. Inclined-groove tread rubber specimens designed to generate negative fluid pressure were prepared and friction tests under glycerol lubrication were conducted. The results showed that the inclined-groove specimens generated negative fluid pressure and achieved a higher friction coefficient than did the rectangular-groove specimen. The results also indicated that a tread block with an inclined-groove shape with a small groove depth is desirable for achieving high adsorption force and friction, and for a given adsorption force, a tread block with a large convex plateau region is desirable. Our research showed that when the groove shape was controlled, the fluid flow could be adjusted to increase the tread rubber friction.
期刊介绍：
Tribology is the science of rubbing surfaces and contributes to every facet of our everyday life, from live cell friction to engine lubrication and seismology. As such tribology is truly multidisciplinary and this extraordinary breadth of scientific interest is reflected in the scope of Tribology International.
Tribology International seeks to publish original research papers of the highest scientific quality to provide an archival resource for scientists from all backgrounds. Written contributions are invited reporting experimental and modelling studies both in established areas of tribology and emerging fields. Scientific topics include the physics or chemistry of tribo-surfaces, bio-tribology, surface engineering and materials, contact mechanics, nano-tribology, lubricants and hydrodynamic lubrication.
