摘　　要：针对长期以来橡胶圈加稳径向气体轴承的偏位角与偏心率在试验中“测不准”、在理论上难以分析的问题,通过引入绝对坐标系与相对坐标系下绝对偏心率、相对偏心率、基础偏心率等若干参数, 提出了一套新颖的对橡胶圈加稳径向气体轴承偏心率与偏位角进行理论分析与试验研究的方法, 并在试验中运用此方法研究了橡胶圈加稳径向轴承的偏心率与偏位角的变化规律及特点。In order to analyze the eccentricity and the attitude angle of journal gas bearing with rubber rings support, some new concepts and parameters were introduced. Based on the absolute coordinate and relative coordinate, the theoretical model and experimental method were developed to solve the geometrical performance of journal gas bearing with rubber rings support. The comparative results of analytical study and experimental test indicate that the proposed theoretical method is feasible.
