The paper was based on load - bearing properties of elementary aerostatic bearing , predigested support and spindle structure of multi - support aerostatic motorized spindle , established finite - element analysis model , analyzed all kinds of structureal designs of shafting refer to ansys software , analyzed and compared load - bearing characteristics 摘要基于單元?dú)怏w靜壓軸承的承載性能,簡(jiǎn)化多支承氣體靜壓電主軸的支承和主軸結(jié)構(gòu),建立了有限元分析模型,借助ansys軟件分析軸系的各種結(jié)構(gòu)方案,并進(jìn)行承載特性分析對(duì)比。
Aerostatic bearings have been applied widely on the ultra - precision in the aviation , aerospace and the main axes and the slide of the precision measuring instrument and inertial measuring apparatus because of high rotation accuracy , calm operation , low friction and long life - span etc . they can also be used in fields range from both high and low temperature to both high and low velocity , sometime even to environment full of radioelement 氣體靜壓軸承回轉(zhuǎn)精度高、運(yùn)轉(zhuǎn)平穩(wěn)、摩擦小、使用壽命長(zhǎng),可以在極高和極低的溫度、超低到超高的速度下,以及輻射環(huán)境中工作,因此在航空、航天領(lǐng)域以及精密測(cè)量和慣性測(cè)試設(shè)備上得到廣泛應(yīng)用。
