采用气体润滑的球形轴承是空间飞行器姿态控制系统三轴气浮模拟台、零部件测试台或其他试验台中的一个关键部件,其性能好坏直接影响设备的使用,在加工中一般要求精度较高、条件比较苛刻,因此在设计计算上必须特别考虑,以期达到较好的性能。本文在计算方法上加以探索,除一般方法计算外,采用有限元法求解。计算的目的是在给定的某一气膜关系(即给定半径差⊿R、浮起量C、水平偏移量e、供气压力Ps、孔数n、孔径d以及θ_2、θ_1和θ_0)的条件下、计算轴承的总承载能力W W=(W_Z~2+W_H~2~)1/2
Gas-lubricated ball bearings are a key component of the spacecraft attitude control system tri-axial flotation simulator, parts testing platform or other test rig, the performance of a direct impact on the use of equipment in the processing of the general requirements of high precision , The conditions are harsh, so the design calculation must be specially considered, in order to achieve better performance. In this paper, the calculation method to explore, in addition to the general method of calculation, the use of finite element method to solve. The purpose of the calculation is to give a given gas film relationship (ie, the given radius difference ⊿R, the amount of lift C, the horizontal offset e, the supply pressure Ps, the number of holes n, the diameters d and θ_2, θ_1 and θ_0) Under the conditions of bearing capacity of the total calculation of WW = (W_Z ~ 2 + W_H ~ 2 ~) 1/2
