Pneumatic Hammer in Aerostatic Thrust Bearings with Single Orifice Compensation

摘要：

　　In dealing with the phenomenon of the pneumatic hammer in aerostatic thrust bearings,the vibrant model of the one-single freedom system has been established to study the pneumatic hammer from the point of sympathetic vibration.It is found that the bearings show a tendency to result in the pneumatic hammer with the increase of air supply pressure,and the occurrence probability of the pneumatic hammer will be reduced when the gas film thickness is maintained within a certain range.Meanwhile,the existence of the pneumatic hammer,which is caused by sympathetic vibration,is experimentally verified,and it is found that gas bearings undergo certain disturbance,which causes the system to produce micro breadth vibration.Accordingly,the micro breadth vibration causes the gas film and thrust face to form flow/structure coupled to excite the pneumatic hammer.Therefore,it provides another path to study the pneumatic hammer and is of academic value.
