【摘要】:在ANSYS中运用APDL语言参数化编程,建立空气静压轴承的三维流场模型;在Workbench环境下将模型导入到FLUENT中,分析微孔阵列式节流器微孔个数、节流器微孔直径以及压力腔的直径和深度对空气静压轴承稳定性的影响。结果表明:采用微孔阵列节流器可以显著减小微振动;随着节流微孔的直径和压力腔直径的减小及压力腔深度的增加,微振动均减小,空气轴承的稳定性提高。
[Abstract]:The use of APDL language programming parameters in ANSYS, 3D flow field model of aerostatic bearing; under the environment of Workbench model is imported into FLUENT, analysis of the effect of micro pore array type restrictor pore number, pore diameter and throttle pressure chamber diameter and depth of air static pressure bearing stability. The results show that the micropore array throttle can significantly reduce the micro vibration. With the decrease of the throttling hole diameter and the pressure chamber diameter and the increase of pressure chamber depth, the micro vibration decreases, and the stability of air bearing improves.
