摘要
介绍了两种评定材料抗接触疲劳能力的指标——应力循环次数和点蚀严重程度标记数。论述了制定接触疲劳失效判定准则的意义。作者通过试验,研究了纯滚动和滚-滑运动接触条件下失效时点蚀坑形式的差异,提出了这两种条件下接触疲劳失效的判定准则。
Two evaluation indexes of the anti-contact fatigue-----
the stress cycles and the marking numbers of pitting damage degree are introduced and the significance on drawing up the judge criterion of contact fatigue failure is discussed. The authors have investigated the difference of pitting damdge types under the contact conditions of pure-rolling and rolling-sliding with experiments and suggested a judge criterion of contact fatigue failure under these two conditions.
