| 摘 要： | 本文研究了裂纹转子的振动响应。文章首先通过应力强度因子积分得到含裂纹轴单元的刚度矩阵；建立了裂纹转子的运动微分方程。进而研究了裂纹转子的振动响应，得出了裂纹转子的振动响应随裂纹位置和深度的变化关系。为工程上早期诊断微小裂纹提供了理论根据。

| Abstract: | In this paper, the vibration responses of cracked rotor are investigated. First, the stiffness matrixof cracked element is derived from the integration of stress intensity factor and the differential equa-tions of motion of a cracked rotor are established. Then, authors calculate the vibration responses ofcracked rotor and get the changing relationship of vibration responses with the depth and location ofcrack. This will provide the theoretical basis for diagnosing little crack early in engineering. |
