J O1brnal of R esearch of the National Bureau ot Standards. Diese Seite übersetzen Table of static and dynamic friction coeffcient and friction equations given in imperial and SI metric units. Coefficient of friction for. Contact and friction between rubber pad and metal sheet.

RUBBER PAD FORMING PROCESSES. I cannot find any exact grade of steel for the.

I have assumed a COF of about 0. This website here says Rubber on steel static friction coeff = 0. Which materials have the highest coefficients of friction. Rubber , Concrete (Dry ). Friction coefficient of Mud and grass 3. Material Contact Properties Table. Learn more about contacts.

Below are provided a small number of values showing approximate values of friction coefficients to be used for steel screw fastened connections.

The values are only representative values and should be confirmed against other sources of information and preferably testing. Static friction from the normal force of two objects in contact, acting opposite the intended motion of one surface against the other. The maximum force of static friction can be calculated by multiplying the normal force by the coefficient of friction specific to the pair of materials in contact.

Thus, the coefficient of static . The coefficient of friction (µ) is a number that is the ratio of the resistive force of friction (Ff) divided by the normal or perpendicular force (Fn) pushing the objects together. COEFFICIENTS OF FRICTION. The two main frictions used . Canvas belt on rubber lagging. Cast iron on asbestos, fabric brake material.

In spite of the large difference in viscosities, the rubber friction coefficients. Ultimately, I think the discrepancies you are seeing are due to differences in conditions. As you probably know, the conditions can change the coefficient of friction enormously. Polishing the metal will usually lower the friction , a lubricant will lower the friction , and the temperature will change the viscosity of . Effect of oxide film etc on coefficient of static friction.

Extreme care is needed in using friction coefficients.
