摘　　要：本文针对静压滑环的结构图建立其密封缝隙的简化模型,在考虑变粘度条件下推导了流量、压力、刚度计算公式,并利用有限元方法得出了静压滑环中密封缝隙的流场特性分布情况。It aims at the structure of hydrostatic slip ring, and builds up a simplified model of hydrostatic slip ring seal clearance. The paper derives the distribution laws of the velocity, press and temperature variable viscosity fluid fields in the clearance, finally obtains the result on fluid field characteristic of seal clearance by finite element analysis.
