摘　　要：给出了一种计算变截面连续质量转子临界转速的传递矩阵法，该方法是基于〔２〕所提方法和Ｐｒｏｈｌ传递矩阵法发展而来的。由于考虑了连续质量模型，使用了低阶数矩阵和方便的递推公式，从而大大提高了计算精度。利用该方法还能方便地考虑转子本身回转贯量及剪切变形对各阶临界转速和振型的影响。A transfer matrix method of the critical speed calculation of cross-section change,continuous mass rotor systems is presented in this paper.It is based on the method presented in 2 and Prohl transfer matrix method.The computational accaracy can be improved by using continuous mass model,low dimension matrix and simplified approaches.When influences of rotating inertia and shear deformation are considered,the convenience of this method shows up.
