Centred on the evaluation of the static rigidity of the spindles in an all-round way, a study of the radial static rigidity of the spindles of machine tools is made by using the "influence factors" method in mechanics.Apart from expressions for the influence factors of the nose of the spindle mounted in two bearings and three bearings under different static-loading conditions, an analysis of the relative parameters for the minmum value of the influence factors and a graphical method for finding optimum parameters (optimum bearing span, optimum distance of the driving element from the front bearing) for spindles mounted in two bearings are given, the proposed method being also suitable for determining the optimum parameters for spindles mounted in three bearings.

In designing gas bearings, the frequency characteristics of the bearing is an important information. For spiral-grooved bearings, perhaps the best known method for the calculation of the frequency characteristics is the narrow-groove theory. But its validity in the case of only a few grooves, say 6 to 12 grooves, is doubtful due to the end and edge leakage effect. The finite difference method and the finite element have been proposed by several authors. But for the former, a fine grid is required and for the...

In designing gas bearings, the frequency characteristics of the bearing is an important information. For spiral-grooved bearings, perhaps the best known method for the calculation of the frequency characteristics is the narrow-groove theory. But its validity in the case of only a few grooves, say 6 to 12 grooves, is doubtful due to the end and edge leakage effect. The finite difference method and the finite element have been proposed by several authors. But for the former, a fine grid is required and for the latter, only method for calculating the static load capacity or stiffness is available. In the present paper, a high order, isoparametric, finite element method for calculating both the static and perturbed frequency characteristics of spiral-grooved self acting gas bearing is proposed, which can drastically reduce the storage and computer Time reguired compared with the existing finite difference and finite element methods.

设计气体动压轴承时,需知其频率特性。目前最有名的是基于窄槽理论的方法。但在槽数较少,例如6至15槽时,其正确性由于端部和边缘效应而受到影响。也有若干作者建议了有限差分和有限单元法。但前者需要很密的网格,后者现仅有计算静载荷和静刚度的方法。本文提出了一个计算带螺旋槽气体动压轴承静态和摄动频率特性的高次、等参有限元方法。它可以比已有的有限差分及有限单元法大大减少所需的储存单元和计算机时。
