本文利用小扰动法分析了轴向缝切向进气径向气体轴承的稳定性问题.在理论分析中考虑了气流的惯性项对该类轴承稳定的影响,得出了轴承的设计参数与轴承失稳转速及失稳涡动比的关系曲线.实验结果与计算结果吻合较好.
In this paper, we analyze the stability of radial gas bearing with tangential inlet in radial direction by small perturbation method, and consider the influence of inertial term of airflow on the stability of this kind of bearing in theoretical analysis, and get the relationship between bearing design parameters and bearing Unstable speed and unstable vortex ratio.The experimental results are in good agreement with the calculated results.
