根据摩擦磨损理论,机器从投入运行开始,各对摩擦副均会发生磨损,产生磨粒,这些磨粒包含着有关摩擦过程和磨损表面状态的重要信息。通过对磨粒量的测试可确定机内磨损状况,对机械设备运行情况实行有效的监控。图1是一般机械系统的磨损曲线。通常可把它分成数段,其中AB为跑合段,BC为正常运行段,CD为异常磨损段,DE为严重磨损段(开始损坏)。由于各种不同的机器结构参数,加工工艺及装配情况,机器的正常与异常临界转拆点C以及损坏点
According to the theory of friction and wear, since the machine is put into operation, the pairs of friction pairs wear out and produce abrasive particles, which contain important information on the friction process and on the worn surface condition. Through the test of the amount of abrasive to determine the machine wear status, the implementation of effective monitoring of the operation of machinery and equipment. Figure 1 shows the wear curve of a typical mechanical system. It can usually be divided into several sections, where AB is the run-in section, BC is the normal operation section, CD is the abnormal wear section and DE is the severe wear section (start of damage). Due to a variety of different machine structure parameters, processing technology and assembly conditions, the machine’s normal and abnormal critical rotation point C and the damage point
