摘要
本文以Hirs紊流润滑方程为基础,应用摄动分析法及数值计算获得了有限长环状密封的转子动力系数,模型中考虑了人口预旋的影响。通过与实验及用有限差分法获得的结果比较,证明本文提出的方法具有一定的实用性。
Based on Hir’s turbulent lubrication equations, the perturbation and numerical calculating meth-ods are used to obtain the rotordynamic coefficients of finite length annular seals,the results are com-pared with other theoretical results and experimental data.It is showed that the numerical method is practical.
