Abstract

Surface tensile stress and internal shear stress are main sources of the fretting fatigue for endless rope winch drum during operation. To probe the distributions and impact factors, the basic theories of microtribology and contact mechanics are applied to derive analytical expressions. Then, numerical simulation is conducted to discuss effects of the friction coefficient, surrounding angle and coefficient of cylinder generatrix. The results indicate that the maximum surface tensile stress increases with the friction coefficient. The influence of surrounding angle is greater. As the coefficient of cylinder generatrix increases close to 1, the increasing trend of maximum surface tensile stress becomes gentle. AS for the maximum internal shear stress, the friction coefficient has little effect. Research results have important theoretical significance for rational design and scientific maintenance of the endless rope winch drum.
