摘要

为了更好地研究箔片轴承的动态特性和稳定性

提高高速透平机械中轴承转子的系统稳定性

采用能量耗散的方法对单层和双层鼓泡箔片轴承的库仑阻尼耗散能量进行了分析与评价

获得了箔片厚度、周向和轴向鼓泡支承点间距等结构参数以及弹性模量对库仑阻尼耗散能量的影响。数值研究结果表明:随着箔片厚度的减小

周向鼓泡间距减小

库仑阻尼耗散能量增加; 轴向鼓泡支承点密度增大以及偏心率和转速的升高也会加强库仑阻尼耗散; 在相同工况下

双层鼓泡箔片轴承的库仑阻尼耗散明显大于单层鼓泡箔片轴承

且改变双层鼓泡箔片轴承中层鼓泡箔片厚度耗散能量效果优于改变顶层平箔厚度; 高弹性模量材料的硬度高

箔片滑移量小

会减小库仑阻尼耗散能量; 相同条件下

鼓泡箔片轴承选用高弹性模量材料时库仑阻尼耗散能量更小。

Abstract

In order to better study the dynamic characteristics and stability of gas foil bearings and improve the stability of the rotor bearing system in high-speed turbomachinery

the energy dissipation method is used to analyze and evaluate the dissipation energy of Coulomb damping in single and double protuberant foil bearings. The influences of foil thickness

circumferential and axial protuberant pitch and elastic modulus on the dissipation energy of Coulomb damping are obtained. Numerical results show that the energy dissipated by Coulomb damping increases with the decrease of foil thickness and the decrease of the circumferential protuberant pitch. The Coulomb damping dissipated energy is enlarged by increasing the density of axial protuberant points and the increase of eccentricity and rotate speeds. The Coulomb damping dissipation effect of double-layer protuberant foil bearing is significantly greater than that of single-layer protuberant foil bearing under the same working condition. Moreover

the effect of changing the thickness of the middle protuberant foil to dissipate energy is better than that of changing the thickness of the top layer flat foil. The material foil with high elastic modulus has higher hardness and less slippage

which would reduce the energy dissipation of Coulomb damping. Less energy is dissipated through Coulomb damping when the protuberant foil bearing is made of materials with high elastic modulus under the same conditions.
