摘　　要：箔片结构作为箔片气体轴承的特殊组成部分,对轴承性能的影响很大。总结国内外学者对箔片结构刚度的研究情况以及库仑摩擦、刚度分布影响箔片结构性能的机制,指出箔片轴承结构发展趋势的理论依据。对一直被忽略的平箔变形问题进行阐述和相应的机制分析。As the special part of air foil bearings,top foil and bump-type foil strip have a high impact on the performance of foil bearings. The progress of researches on calculations of stiffness made by domestic and foreign scholars was summarized, illustrates that how the effect of friction and stiffness distribution on the property of foil bearing was illustrated and the theory basis for trends in foil structure design was pointed out. The deformation of top foil which is used to be ignored was investigated.
