| 摘 要： | 针对转轴裂纹疲劳扩展所具有的从相对稳定到失稳扩展这两种状态，提出用实时的振动检测方法来监测相对稳定状态，用非实时的电位法对失稳扩展的裂纹进行检测，预报的转轴裂纹疲劳扩展监测方案。研究结果表明，该方案具有实用化的基本条件。同时，发现了一个新的敏感指标。

| Abstract: | From studying on the rotating shaft crack variations from relative stable status to unstable propagation, a real time method to monitor fatigue propagation of the transverse crack in a rotating shaft is presented, in which relative stable status is monitored by real time vibration measurement and unstable propagation of the crack is monitored by unrealtime dc-potential method. The results show that the method has essential practical conditions. Meanwhile, a new sensitive index is found. |
