| 摘 要： | 由于气体的可压缩性，惯导测试设备上的空气静压轴承，在工作中常发生气膜振荡而严重影响主轴刚度和运动精度。本文深入研究了在阶跃载荷及交变载荷作用下，轴承气膜的过渡特性及动刚度特性，为分析空气静压轴承的动态特性提供了理论根据，并成功地解决了转台轴承的稳定性问题。 |
| 关 键 词： | 空气静压轴承，动态特性 |

| Abstract: | For the reason of compressibility the aerostatic bearing in the appa- ratus for navigation measurement may produce air - film , which can decrease the rigidi- ty and moving precise for shaft . In this paper , the transient haracteristics and dynamic rigidity characteristics of air - film in the bearing are studied under the step load and al-ternating load , which have proposed a theoretical basis for the dynamic characteristics analysis of problem of the aerostatic bearing stability of a turn table. |
| Keywords: | aerostatic bearing dynamic characteristics |
