Transient slider-disk contacts in the presence of spherical contamination particles

摘要: Transient thermal–mechanical contacts between a slider and rotating disk in the presence of contamination particles are investigated using finite element analysis. The maximum temperature rise due to frictional heating, plastically deformed area, residual penetration into surface determined as function particle properties for aluminum glass substrate. It is found that contact with soft deformable can cause large rise, sufficient thermal erasure, even though physical damage media not observed. Contact hard rigid lead severe plastic deformation well high media, representing worst case tribological integrity slider-disk interface.
