摘要
本文简述了七十年代末以来,世界各国力学界对具有裂纹的转子——轴承系统动态特性研究所取得的大量成果,分析了振动监测用于旋转机械故障诊断的可行性,指出存在问题及今后继续研究的方向。
Achievements of scientists in the world since 1970's in studying the dynamicbehaviours of a rotor-bearing system containing cracks are prerented in the paper.The feasibility of detecting cracks in a rotating machine by using the vibrationmethod is discussed. The remaining problems and the trends in the field are alsopointed out.
