光滑及沟槽密封的转子动力学分析及计算

ROTOR DYNAMIC ANALYSIS AND CALCULATION FOR SMOOTH AND GROOVED SEALS

参考文献［１］，将Ｈｉｒｓ紊流整体流动理论进行扩展，在Ｃｈｉｌｄｓ环形密封有限长解的基础上，引入平均槽深，并研制出计算程序，对光滑密封和沟槽密封动特性系数及泄漏流量进行了分析计算，对沟槽密封的复数常微分方程组进行求解。

In this paper,relying on [1],an extension of bulk flow theory is derived, and this theory is based on the finite length solution for annular plain seals in which an average grooved depth is introduced. A computer program to calculate rotordynamic coefficients and leakage of smooth and grooved seals is designed,in which,solutions of complex ordinary differential equations have to be solved for grooved seals are involved.
