High stress is caused by sliding in the process of the line-contact has a great influence on its service life. Through establishing a finite element 3D model of the cylinder-plane friction couple for dynamic contact, ANSYS/LS-DYNA is used to analyze the friction pair’s stress in the condition of rolling-sliding. The stress state of the friction is compared in the condition of five different slide-roll ratios by numerical simulation. The results show that the friction’s stress in the dynamic condition of rolling-sliding is rather bigger than in the static condition. Comparing the average value and the maximum value of the von mises and shear stresses in five different slid-roll ratios situations, it can be found that the values of max and average both first increased then decreased with increasing of the slide-roll ratio and the maximum values both appeared at the slide-roll ratio of 0.1. Methods and conclusions can provide some references for the research of the line friction pair’s dynamic contacting nature in the condition of rolling-sliding and the prediction of the friction pair’s service life.
