本文开发了一种具有开放裂纹的有限元转轴模型的振动分析方法，该方法是在我们之前的研究中开发的。特别研究了含裂纹转轴在谐波激励下的振动问题，推导了含裂纹转轴振动的基本方程。通过将理论结果与实验结果进行定量比较，验证了分析方法和推导出的基本方程的有效性。这一结果有助于在转子的早期阶段检测出裂纹。
©2013 The Japan Society of Mechanical Engineers This paper develops an analytical method of the vibration of the finite element rotating shaft model with an open crack which was developed in our previous study. Particularly, the vibration of the rotating shaft with an open crack under the harmonic excitation is investigated, and the fundamental equations governing the vibration of the cracked shaft are derived in that case. By comparing the obtained their theoretical results with the experimental results quantitatively, the validity of the analytical methods and the derived fundamental equations are verified. This result contributes to detect a crack of a rotor in its early stage.
