Prediction of Contact and Lubrication Characteristics of Micro-textured Surface Under Thermal Line Contact EHL

摘要: In this study, a method combining numerical surface generation technology and three-dimensional hot-line contact EHL is employed to evaluate the characteristics of micro-textured surfaces under high-load line contact. Based on simulation, film thickness, pressure, friction coefficient flashing temperature virtual texture with different cross-sectional shapes sizes are studied. On basis, subsurface stress at point calculated by DC-FFT algorithm. The results show that, compared smooth surface, micro-textures all increase average oil thickness reduce coefficient, but same time lead an in surface. By changing width depth texture, maximum pressure has changed 11.4% 18.5%, respectively.
