Results show that instantaneous friction coefficient does not keep constant even under steady exterior micro-load due to tribo-structure and manufacture error,and it varies with operation condition such as type of lubricants,rotation speed of shaft,exterior load and oil starvation state.

Results indicated that higher precipitated calcium carbonate (PCC) ratio to clay in mixed pigments resulted in higher static and dynamic friction coefficient.

Through analyzing the testing methods of dynamic friction coefficient between road surface and tire,the rationale of testing road surface friction coefficient and structure characteristics of testers are described,and the effects of the traveling speed and road condition on the friction coefficient are investigated.
