本文建立了三体磨粒磨损的计算模型,这与通常所作的关于磨粒磨损主要是由切削引起的假设不同。在该模型中,仅考虑磨粒对金属表面产生塑性变形的相互作用。文中指出,在滑动和切削过程中重复产生变形会造成金属磨损。这时,低循环疲劳似乎是主要的磨损机理。 This paper establishes a three-body abrasive wear calculation model, which is generally made on the abrasive wear is mainly caused by the hypothesis is different. In this model, only the interaction of the abrasive grains with the plastic deformation of the metal surface is taken into account. The article pointed out that in the process of sliding and cutting repeated deformation will cause metal wear. At this time, low cycle fatigue seems to be the main mechanism of wear.
