CONSTRUCTION OF FRICTION FEATURES OF FRICTION MOVEMENTS OF BRAKE MECHANISMS IN THE VIEW OF THIRD-ORDER POLYNOMIAL MODELS
The concepts of frictional characteristic of the brake mechanism and frictional characteristic of the friction pair of the brake mechanism, which are necessary for the calculation of the real braking properties of vehicles, are considered. An experimental device has been developed to determine the influence of such destabilizing factors as temperature, sliding speed and contact pressure on the mentioned characteristics. A method for obtaining polynomial models of the third order to determine the effect of temperature, sliding speed and contact pressure on the coefficient of friction in the friction pairs of brake mechanisms is proposed. The technique is suitable for cases when the second-order models inadequately describe the effect of these destabilizing factors on the coefficient of friction in the friction pairs of brake mechanisms.
