摘要

针对某柴油机活塞销孔的磨损问题，分别借助有限元方法和EHD仿真方法研究了不同销座结构匹配多种销孔型线对接触应力的影响，及不同活塞销孔型线对润滑特征评价参数的影响。综合研究表明，活塞销孔型线与热变形匹配不合理所引起的润滑状态恶化是导致活塞销孔磨损的直接原因，因此通过合理调整销孔型线可使接触应力均匀，润滑状态良好，并有效降低活塞销座磨损风险。

Abstract

In order to solve the wear problem of piston pin hole
for a diesel engine, the FE and EHD methods were used to analyze the influence
of piston pin hole structure and profile matching on the contact stress and the
influence of different profiles on lubrication evaluating index. The results
show that the direct reason of scuffing problem is the worse lubrication
resulted by the mismatch between profile and thermal deformation. Accordingly,
homogeneous contact stress, good lubrication and low risk of scuffing can be
obtained by matching a reasonable profile for piston pin hole.
