本文在较合理的假设的基础上,采用集中质量的离散系统的力学模型,用传递矩阵法来计算汽轮机扭曲叶片的动频。考虑了扭曲叶片的弯曲扭转耦合振动的影响。介绍了状态矢量间的递推关系式。
Based on a reasonable assumption, this paper uses the mechanical model of a discrete system with concentrated mass and calculates the moving frequency of the twisted blade of the steam turbine by using the transfer matrix method. The effect of bending torsional coupling vibration of the warped blade is taken into account. The recurrence relations between state vectors are introduced.
