摘要
建立了球面螺旋槽气体动静压轴承的微气膜有限元模型,应用CFD技术和流体动力学Fluent软件,研究了球面螺旋槽气体动静压轴承在稳态下的承载特性,得到了轴承在不同转速下的压力分布云图,进而揭示了在不同运行参数和结构参数下,轴承承载力及动静压耦合效应的变化规律。结果表明,选择合适的结构参数和运行参数,如槽宽比、槽深比、螺旋角、槽数、转速等,有助于提高轴承的承载性能。
This paper build the micro gas film model of spherical spiral groove hybrid gas bearings, and with the science of CFD and the fluid dynamics software Fluent, the hybrid gas beating＇s bearing capacity under steady state was analyzed. And get taken out the stress distribution nephogram under different revolving speed. By this account, the change regularity of bearing capacity under different operation parameters and structure parameters was re- vealed. The results show that choose the appropriate structure parameters and operation parameters, such as the groove width ratio, groove depth ratio, helix angle, groove number and speed etc, can help to improve the bearing performance of bearing.
