摘要：为了分析连杆小头衬瓦的磨损与缸套上缘的点蚀之间的关系，从衬瓦摩擦原理和活塞的横向振动对缸套的影响原理出发，推断了衬瓦在上止点摩擦的状态及其与活塞横向摆动的关系。并通过量化衬瓦磨损状况和缸套上缘磨损状况以及分析两者量化量的相关性证明了两者的关系，结果表明两者存在较强的关联性以及偏磨对两者相关性有影响。

Abstract：In order to analyze the relationship between the wear of
liner in the small end of the connecting rod and the pitting on the upper edge
of the cylinder sleeve,the friction state of the liner at the top dead ceuter
and its relation with the lateral swing of the piston are deduced from the
friction principle of the liner and the influence of the lateral vibration of
the piston on the top dead ceuter.And by quantifying the liner wear and the
pitting on the upper edge of the cylinder sleeve and correlation analysis
between quantitative proofs of the relationship between them,the results show
that the strong correlation and correlation effect of partial wear.
Key words：Liner in the small end of the connecting rod;the upper
edge of the cylinder sleeve;wear;corrclation
