结构刚度和阻尼对箔片轴承承载力的影响
首发时间:2005-12-07
摘要:影响箔片轴承广泛应用的一个关键问题是其承载力不足。结构刚度和阻尼是箔片轴承承载力的主要影响因素。本文从承载力系数出发,分析了箔片轴承在周向、轴向和径向三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

The Effect of Structural Stiffness and Damping on the Load Capacity of Foil Bearing
Abstract:One key technical hurdle for the further application of foil bearing lies in its low load capacity, which is mainly depended on the structural stiffness and damping. Using the concept of load capacity coefficient, the variations of structural stiffness in circumferential, axial and radical directions on the performance of load capacity of foil bearing are analyzed specifically. 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 are compared through load capacity coefficient
Keywords: Foil Bearing, Load Capacity, Structural Stiffness, Damping
