摘　　要：为解决地面模拟空中飞行控制装置的支承问题,试制了气体静压万向球轴承。首先借鉴已比较成熟的气体静压轴颈轴承和气体静压止推轴承的设计方法,根据拓扑理论和力系等效原理将球体转化为等效的圆柱体,对气体静压球轴承进行近似设计。最后应用该设计理论,成功加工出气体静压球面轴承。An all-direction aerostatic ball bearing is made to solve the supporting problem of groundbased simulating device of air flight control. Firstly, the sphere of ball bearing is transformed into an equivalent cylinder based on the topology and equivalent principles of force system during the design stage, then the design method of aerostatics radial and thrust bearing can be carried out for that of the all-direction aerostatie ball bearings. Finally, an all-direetion aerostatie ball bearing is suceessfully produced based on this method.
