| 摘 要： | 本文提出横向裂纹转子的可变抗扭刚度概念,建立参数扭振的单自由度动力学模型,从而指出裂纹转子在一定条件下存在扭失稳现象。在实验室条件下,作者对真实裂纹转子在不同联接条件下进行了试验,结果表明,裂纹转子存在参数扭振动现象。

| Abstract: | Based on the concept of variable torsional stiffness of rotor with a sectional crack,thesingle degree freedom model of parametric torsional vibration is proposed.By means of a ro-tor with a true sectional crack,the behaviour of parametric torsional vibration is verified indynamic test. |
