In this paper, a kind of fluid vibration in 3-dimensional sealed rotor with axis of rotor as original point under cylindrical-coordinate system is researched.Based on four kinds of edges hypothesis, a 3-d gas vibration e-quation is deduced,and fluid-structure coupling vibration characteristics in the system is analyzed.
