Friction coefficients and grasp synthesis
2013 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2013We propose a new concept called friction sensitivity which measures how susceptible a specific grasp is to changes in the underlying friction coefficients. We develop algorithms for the synthesis of stable grasps with low friction sensitivity and for the synthesis of stable grasps in the case of small friction coefficients.

Robust Estimation of Road Frictional Coefficient
IEEE Transactions on Control Systems Technology, 2011Vehicle active safety systems stabilize the vehicle by controlling tire forces. They work well only when the commanded tire forces are within the friction limit. Therefore, knowledge of the tire/road friction is important to improve the performance of vehicle active safety systems.

The Journal of the Royal Aeronautical Society, 1949
SummaryA summary is presented of information collected on coefficients of friction (rolling and sliding) between rubber tyres and road or runway surfaces. Nearly all the data collected are from tests on automobile tyres and are limited to speeds of about 40 m.p.h.

Coefficient of Friction of Watermelon
Transactions of the ASAE, 1996The static and dynamic coefficients of friction for two watermelon cultivars against six different surfaces were measured at three sliding speeds and three normal forces. The sliding speed, measurement (harvest) date, and type of abrasive surface had a significant effect on both coefficients, except sliding speed did not affect the dynamic coefficient ...

The Coefficient of Friction of Rubber
Rubber Chemistry and Technology, 1935Abstract Coefficient of friction is defined as the ratio of the force of friction to the load producing it. The accepted laws of the coefficient of friction are: 1. It is independent of the area of the surface in contact. 2. It is independent of the load applied. 3. It is independent of the velocity, at low values. 4.

Coefficient of friction for a sphere
American Journal of Physics, 1984A ball that rolls on parallel tracks, whose width is less than the diameter of the ball, experiences both translational and rotational motions. The linear accelerations of the ball for cases of rolling and slipping are derived theoretically, and these accelerations have also been determined by performing experiments when the width and the angular ...

The coefficients of friction and wear
Il Nuovo Cimento, 1958The combination of the Savage surface energy and the Bowden and Tabor junction formation mechanisms of production of frictional energy is suggested. The physical description of the experiments is sufficiently simplified and represented by a stable state which envelopes the whole field of friction.

Nature, 1941
THE ordinary static friction apparatus with one mass m hanging over a pulley and connected to another mass M resting on the friction board may be used to determine the kinetic coefficient. Let m be more than sufficient just to move M, and let h be the vertical height over which m is allowed to accelerate M; then, if x is the extra distance along the ...

The coefficient of friction of metals
Wear, 1958Abstract To explain the increase in the area of contact, and hence in the adhesion, of a steel ball sliding on indium, McFarlane and Tabor produced an analysis based on the interaction of the normal and tangential stresses applied during sliding.
