Experimental Investigation of Influence of Normal Pressure on Rotational Friction Behavior

From various previousexperimental researches, the stable hysteresis of brake liningpads-to-stainless steel sheet friction interfaces has been verified.However, most of previous researches concentrated on the linear frictionbehavior of the brake lining pads-to-stainless steel sheet interfaces andresearches on rotational friction behavior are very limited. Therefore, thisstudy experimentally investigates the rotational friction behavior of theinterfaces and the influence of normal pressure applied by torque ofhigh-strength bolts. Cyclic loading tests were carried out with changing normalpressures.
