- Abstract
In this paper, the static and dynamic equations of the blade are derived, the comparison between analytical method and finite element analysis results. Finding the error of the two methods is less than 1%. The influence of the distribution characteristics of the blade crack on the static and dynamic frequency was studied by using ANSYS software. The result shows that the influence of crack direction on frequency is similar, the effect of the different speed on the dynamic frequency of the blade is not the same.With the change of crack position, the dynamic and static frequency of the blade decreases and then increases.The deeper the crack depth, the lower the dynamic and static frequency of the blade.
