当相接触的两物体有相对运动或相对运动趋势时,在接触面处必有与相对运动方向相反的阻力——摩擦力;在相对运动中,必有接触表面材料不断地微量脱落——磨损;人们为了减少阻力,减缓磨损,而采取一定的利用第三种材料的措施——润滑。所以说摩擦力和磨损是广泛存在的,润滑是针对摩擦力和磨损而存在的(虽然润滑还可达到其他目的)。对此,一般称为摩擦、磨损和润滑问题。很久以来,人们就在不同学科领域内解决着这些问题,积累了不少有关资料。但是对摩擦力的产生及磨损的形成机理,至今尚未完全解决,尚未提出具有普遍意义的、符合实际的、可指导实践的摩擦力和磨损的动力模型。因而,润滑问题也就有它的局限性。为解决此问题以便更好地推动生产,十几年来已逐渐形成一门新的边缘学
When the two objects in contact with the relative movement or relative movement trend, at the contact surface must have the opposite direction of the relative movement resistance - friction; in the relative movement, there must be a trace of the contact surface material off - wear and tear ; People in order to reduce resistance, reduce wear and tear, and take some measures to use the third material - lubrication. So friction and wear are widespread and lubrication is for friction and wear (although lubrication can be used for other purposes as well). In this regard, it is commonly referred to as friction, wear and lubrication problems. For a long time, people have solved these problems in different disciplines and accumulated a lot of relevant information. However, the formation mechanism of friction force and wear has not been completely solved so far, and no common, practical and instructive dynamic model of friction and wear has been proposed yet. Therefore, the lubrication problem also has its limitations. In order to solve this problem in order to better promote the production, more than a decade has gradually formed a new edge of learning
