本文给出了从边界条件着手考虑叶根柔度影响的汽轮机叶片组的振动计算方法.计算结果与实测值和牢固系数修正方法的结果进行了比较.讨论了叶根柔度对不同振型和不同结构叶片振动的影响.以及各个柔度系数对叶片固有频率的影响.
In this paper, the calculation method for the vibration of steam turbine blade set considering the effect of root flexibility on the boundary conditions is given. The calculated results are compared with the measured values and the results of the correction method of solid coefficient. The influence of different structure blades vibration and the influence of each flexibility coefficient on the natural frequency of blade.
