摘　　要：本文研究了考虑三维接触状态的迷宫气封模态的计算方法;通过建立接触面刚度矩阵来模拟阻尼套筒对迷宫气封固有振动特性的影响;结果表明该方法对迷宫气封模态计算是行之有效的。The calculation method of mode of labyrinth gas seals with damping sleeve in threedimensional contact is discussed.The stiffness matrix is built to simulate he influence of damping sleeve to labyrinth gas seals. The results show that this method is effective for the mode calculation of labyrinth seals.
