VARIABLE FRICTION

FIGURE 26.32 Braking and side force coefficient as function of the longitudinal slip for a set slip angle of 8° on wet asphalt at a constant speed of 30 mph, obtained with the Mobile Traction Laboratory (MIL) of the NHTSA. The curves were fitted using the brush model for composite shp with a variable friction coefficient. [Pg.714]

Introducing the general correlation for the friction factor suggested by Churchill (11), figure 2 shows how the choking conditions now depend on the pipe length for isothermal conditions and variable friction factor. As it is seen, the effect of the variable friction factor is negligible. [Pg.183]

In the case of Langevin dynamics with different, variable friction coefficients for each particle, we have S = Me and... [Pg.239]

A variable friction coefficient is introduced dependent on Reynolds number and therefore indirectly dependent on viscosity and tempera-mre. Using Eq. 13, the efficiency results for various entry temperatures and shock strengths have... [Pg.2990]

A change of temperature can help to keep the stock on one particular roll. Often the front roll is made into the faster one by a change of gearing, but in a mill room which has a wide range of stocks it is always a problem. The use of mills with variable friction ratio, with hydraulic drives to achieve this, are being specified at this time. [Pg.214]

In order to account for the very small and variable friction coefficient observed with solid film lubricants, Bowers and Zisman suggested that is was necessary to take into account the pressure dependence of the shear strength of the solid lubricant, and proposed the empirical equation... [Pg.180]

The concept of variable friction drives is described and a comparison is made between frequency controlled AC and hydraulic drives. Some of the features and benefits of using hydraulic drives on a roll mill and mixer are ontlined and a functional description is given of a radial-piston type motor with a rotating cylinder block/hoflow shaft and a stationary motor case/housing (Hagglunds Marathon motor).
