中文摘要
      通过详细推导,论证了故障可分离是客观存在的,并就存在过程扰动的连续线性系统和连续非线性系统给出了形式上一致的系统故障可分离的条件.还结合552732QT型电力机车、韶8电力机车、SS4G 0446机车的轮对轴承故障进行了故障分离的具体实践.
英文摘要
      Through the detailed derivation, this paper proves that the separability is objective existence and gives the form unity conclusion in the condition of the fault separation about serial linear system and serial nonlinear system when exist the process noise. This paper also combines the wheels bearing fault of 552732QT electric locomotive, Shao guan 8 electric locomotives, the locomotive SS4G 0446 of the concrete practice of the fault isolation.
