摘　　要：从承载力系数出发,分析了箔片轴承在周向、轴向和径向3个空间方向的结构刚度的变化对箔片轴承承载力的影响。箔片轴承的阻尼主要表现为库仑摩擦阻尼;阻尼的增大使轴承结构刚度增大,稳定性提高,承载力增大。本文还以承载力系数为依据,比较了提高箔片轴承承载力的方法。Using the concept of load capacity coefficient, the effect of the variations of structural stiffness in circumferential, axial and radical directions on the performance of load capacity of foil beating were analyzed. And the increase of damping, demonstrated mainly in the form of column frictional damping results in increased structural stiffness and load capacity, along with the improved whirl stability. Different means to improve the load capacity were compared through load capacity coefficient.
