摘要

为研究不同拱箔成型工艺对弹性箔片气体轴承静、动态性能的影响

对理想拱箔及3种不同成型工艺加工出的拱箔支承的箔片轴承进行了静、动态性能的计算

3种工艺重点对比箔片固定方式及加载卸载速度。采用有限元方法

获得了不同成型工艺下拱箔的型线及厚度分布; 采用有限差分法

耦合箔片轴承结构变形方程与压力控制方程

通过积分得到了轴承承载力; 使用小扰动法计算了箔片轴承刚度系数及阻尼系数。分析结果表明:拱箔的成型工艺会对箔片轴承静、动态性能构成一定影响

相比于理想拱箔

各种拱箔成型工艺均会造成箔片性能的下降; 厚度与型线更为均匀的拱箔支承的箔片轴承承载力更高、稳定性更强; 在拱箔冷压成型过程中

箔片固定方式对拱箔性能的影响较大

加载及卸载速度对拱箔性能的影响较小; 在实际生产过程中

建议的拱箔冷压成型工艺为箔片一端压边固定一端自由

采用适中的加载及卸载速度。

Abstract

To analyze the influence of bump forming process on static and dynamic performances of foil gas bearing

undergoing three different bump molding processes

the behaviors of gas bearing with ideal bump structure are evaluated to emphatically compare the foil fixing modes

loading and unloading rates. The bump profile and thickness distribution for different forming processes are obtained with finite element method

and the coupled deflection equation and pressure governing equation are solved with finite difference method. Then the capacity of gas bearing is calculated by integration

the stiffness coefficients and damping coefficients are sought out with perturbation method. The results indicate that bump forming process affects the static and dynamic performances of foil bearing. Compared with the ideal bump

all kinds of bump forming technology lead a worsened bearing performance. The bump with uniform thickness and profile has stronger capacity and higher stability. In the molding process

the foil fixing modes exert obvious influence on the bearing performances

but the loading and unloading rates almost do not. For the actual bump production

it is suggested that one end of foil is fixed and another end keeps free at moderate loading and unloading rates.
