摘　　要：本文就上瓦开周向槽椭圆轴承的性能进行了试验和理论计算研究,试验结果与理论计算结果相比,前者的K_(eq)大于后者,前者的γst^2小于后者,即由此得出重要结论:前者的失稳转速高于后者的失稳转速。In this paper,both experimental studies and theoretic calculations ofthe characteristics of the elloptical bearing whose upper pad has circumferentialoil groove have been described.By comparing the results of experiment with the-ory,it is shown that the K_(eq) of the former is larger than that of the later;theγ_(at)~2 of the former is smaller than that of the later,and so on.
