摘　　要：建立了计算弹性薄壳的非线性大变形方法 ,并将此方法用于求解悬臂式薄片动压气体润滑轴承的薄片弹性变形 ,通过实验验证并与其它计算方法相比较 ,表明本文所采用的方法是准确 ,可靠的 。In the paper, we present an analysis of th calculation of the foil elastic deformation of gas lubricated foil journal bearing. The theoretical result is based on the solution of shell nonlinear deformation of the foil. The experimental study shows that the numerical results are in good agreement with the experimental data. The analysis results indicate that comparedwith other methods,the analysis method in this paper is more accurate and more reliable.
