摘　　要：采用一种将柔度系数法、谐波平衡法与求解摩擦力的数值跟踪法相结合的时频转换方法,对迷宫气封结构的响应进行了计算.对阻尼套筒摩擦片沿周向和轴向的不同分布对结构减振效果的影响进行了分析,并得出相应结论.The response calculation of labyrinth gas seals with damping sleeve is done by the time-frequency transition method, which includes of the merits of harmonic balance method, dynamic softness method and tracking motion method. The influences of shock absorption on structure are analyzed when the distributing of friction slices is changed along circle and axial direction, then the results are presented.
