| Abstract Scope |
Reciprocating sliding is characterized by frequency and stroke,with sliding velocity distribution maximum at stroke middle and minimum at stroke ends. As sliding velocity is given by 2×frequency×stroke, there are a number of combinations that satisfy above-mentioned sliding velocity. Different combinations of frequency and stroke should have different effects on friction in reciprocating sliding. Effects of frequency and stroke on friction of marine cylinder liner materials were studied on an SRV reciprocating tester by comparing frictional changes under a combination of higher frequency and smaller stroke with those under a combination of lower frequency and larger stroke in a same sliding velocity. It was made clear that in severe
lubricating conditions, higher frequency served to roughen surface roughness increasing friction, while it prompted run-in in improved lubricating conditions lowering friction with opposite frictional behaviors under a combination of lower frequency and larger stroke. |
