文摘A numerical model and a solution method to analyze the labyrinth seal now induced vibration by Oscillating Fluid Mechanics Method (OFMM) are presented in this paper, including the basic equations and solution procedure to determine the oscillating velocity, pressure and the dynamic characteristic coefficients of Labyrinth seal such as the stiffness coefficients and damping coefficients. The results show that this method has the advantages of both less time cousuming and high accuracy. In addition,it can be applied to the field diagnosis of the vibration of the axis of turbomachinery system.
