摘要
本文针对迷宫气密封,利用两控制容积模型导出了基本方程;基于有限差分法得到了控室中回流速度,并将其引入模型之中,用摄动方法得到了密封的刚度、阻尼系数。结果比以前的单控容积模型更接近于实验值。
The basic equations for lbyrinth seal is derived from the volumetric Model ofarea control.Based on finite differnce method,reflux rate in cavity is calculatedand introduced into the model.Sealing stifiness and damping coefficient is alsocalculated with perturbation Method.The results is Much more close to the experi-mentl values than that got by only controlling area.
